Youri Tielemans' thunderbolt strike sealed Leicester's maiden FA Cup triumph with a gritty 1-0 win over Chelsea at Wembley.
The Belgium midfielder rifled an unstoppable effort into the top corner from 25 yards, as Brendan Rodgers' Foxes put another genuine stamp on years of recent quality.
Former Leicester full-back Ben Chilwell saw a last-gasp Chelsea effort ruled out for offside after a video assistant referee review, while Kasper Schmeichel earlier made a superb save to deny Mason Mount.

Leicester's Premier League title win of 2015 might have come against all possible odds, but the east Midlands men have never since wilted.
The Foxes were contesting just their first FA Cup final since 1969, when the Beatles were number one with Get Back and Neil Young's goal sunk the hopeful Foxes - and an eight-year-old Gary Lineker cried all the way home on the train.
The only tears of Leicester blue this time out were of joy and relief however, as Rodgers' men capitalised on Chelsea's toothless final-third play.
Chelsea's second FA Cup final defeat in as many years will now put a major squeeze on the end of the Blues' season.
New boss Thomas Tuchel has transformed the Stamford Bridge men after replacing Frank Lampard on January 26 but Chelsea now face a dogfight to secure a top-four Premier League finish - that starts with hosting Leicester on Tuesday night.
The Champions League final against Premier League champions Manchester City on May 29 in Portugal must now seem an age away for Tuchel and his luckless Blues.
And for the likes of Mason Mount and Reece James, two FA Cup final losses in succession will be a bitter pill after such a resurgent second-half to this campaign.
A number of fans booed the players for taking the knee before kick-off, though the anti-racism gesture also received warm applause.

Timo Werner raced in behind the Leicester defence almost at will in a first half where the Blues dominated but failed to make any of their raids count.
James produced an expert block to thwart Jamie Vardy in the area, after Timothy Castagne had outstripped Marcos Alonso down the right.
Caglar Soyuncu twice nodded over as the Foxes pressed their claims too however.
Werner blasted high and wide from distance after fine work from Jorginho and the ever-excellent N'Golo Kante.
And then captain Cesar Azpilicueta went close but failed to connect with an attempted header with the goal at his mercy. Thiago Silva's teasing cross only required the finest of touches, but Azpilicueta could not adjust quickly enough at the far post after the faintest of flicks from Werner.

Jonny Evans then trudged out of the match just past the half-hour, with his troublesome heel injury again flaring up and Marc Albrighton joining the fray.
Vardy found time to flick a speculative header wide after Tielemans' ball over the top.
But despite Kante stealing the ball in the Leicester area to tee up another period of Chelsea pressure, a cagey affair reached half-time without score.
Chelsea again dominated when the action resumed, but again the Blues had nothing whatsoever in the way of killer instinct.
Alonso headed straight at Schmeichel and with no power from a Kante cross, while Azpilicueta miscued a centre of his own, straight to the untroubled Foxes keeper.

And just when Tuchel must have been preparing a clutch of changes, up stepped Tielemans with a piledriver strike.
Ayoze Perez cut out James' hopeful ball out of defence and Luke Thomas immediately threaded through to the unmarked Tielemans. The Belgium midfielder strode forward and as the space opened up he lashed the ball into the top corner.
The lucky Leicester fans inside Wembley rightly leapt into delirium, to toast a strike of the highest quality.
Tuchel immediately unloaded his bench in a bid to turn the tide, with Chilwell's header forcing a smart save from Schmeichel.
Schmeichel came to Leicester's rescue again at the death, when the sharp-witted stopper tipped away a rasping effort from Mount.
Chilwell thought he had rescued an equaliser against his former club, only to see his bundled effort ruled out for offside by a VAR review.
Prince William hands Kasper Schmeichel the trophy, the Dane makes his way to his team-mates and alongside Wes Morgan holds the famous trophy into the sky and the party begins for Leicester!
The Leicester players are collecting their medals from a tray here, with social distancing in place, as we near the trophy presentation.
Every single Chelsea player is on the pitch watching on.
Kasper Schmeichel: It is an amazing feeling
I'm so happy, I cant begin to describe it. I want to say hello to my kids and wife at home, it is a shame we cant all be here today but what a day.
Amazing, undescribable. it is what dreams are made of. We talked about wanting to win trophies and the grit and determination today. so proud of everybody. Everybody has been sensational.
That's why when you work together and do things properly you have that belief that you can achieve.
Youri, wow, what a finish. I didn't even dare to celebrate it because of VAR but yeah, what can I say. Today is an amazing day and we will enjoy it thoroughly but we are training again tomorrow. Tomorrow we can't really think about it anymore because they will want revenge.
The players are running towards their fans who are basking in the glory at Wembley. Fantastic scenes and extraordinary for Leicester supporters who have longed for this trophy.
FULL TIME - LEICESTER HAVE WON THE FA CUP!
Michael Oliver blows his whistle and the game is over - Leicester City are FA Cup winners for the first time in their history!
Brendan Rodgers lets out a roar of celebration and hugs his technical staff, what a huge achievement for the Northern Irishman.
The fans are crying in the stands and so is Jamie Vardy, who put in a mammoth performance up front.
They had to ride their luck in the end with a couple of outstanding saves from Kasper Schmichel and a controversial VAR decision, but it's Youri Tielemans' strike that has won it and what a strike it was - worthy of winning any FA Cup!
A special, special day for this club in front of their returning fans.
90+3 mins: Soyuncu tries to run the clock down after falling to the turf following a collision with Giroud.
An equaliser is slowly drifting away from Chelsea, who look heartbroken by that VAR decision.
THE GOAL HAS BEEN DISALLOWED!
Replays show that Ben Chilwell was marginally offside when the ball was played by Silva, and Oliver signals that the goal will not count.
A lifeline for Leicester
Chelsea have equalised! Thiago Silva picks out the run of Ben Chilwell, who lands the ball perfectly on his foot. The full back taps the ball past Schmeichel and Wes Morgan fails to clear and the ball is in the back of the net!
But hold on.. VAR
87 mins: Big chance Chelsea! And a world class save from Schmiechel. A cross is headed to Mount who hits the ball so sweetly and looks destined to hit the back of the net but Schmeichel gets a finger tip to the ball and saves!
Mount cannot believe it!

Tuchel is set to make another double change. Havertz replaces Jorginho. Hudson-Odoi is on for Azpilicueta.
68 mins: There is a cacophony of noise coming from the Leicester end now. They are 25 minutes or so away from a famous victory. Replays of the goal show that Perez did not handle the ball in the build up.
Both coaches make subs now. For Leicester, Iheanacho is off for Maddison.
For Chelsea, Pulisic and Chilwell are on for Ziyech and Alonso.
65 mins: Ziyech tries to emulate Tielemans' effort but his strike takes a deflection behind for a corner. They haven't got going this second half and need this wake up call. Corner is cleared by Fofana.
Leicester are ahead in the FA Cup final! And this will go down as one of the FA Cup's greatest strikes.
Perez cuts out a forward pass from Christensen and Tielemans latches onto it. 30 yards out from goal the Belgian shoots from range and rifles the ball into the top corner leaving Kepa with no chance.
A special goal for a special game!
63 mins: Chelsea enjoy a foray forward as Kante drives upfield and plays the ball to Azpilicueta, but the captain's ball into the box is poor and Schmeichel collects.
61 mins: Albrighton forces another corner as Leicester fans roar their side on, those players are certainly responding. Can they make this good spell count?
A short corner is played and the opportunity is wasted.
56 mins: Iheanacho plays the ball back to Tielemans who fizzes in a wicked ball towards Vardy but James is alert to the danger and turns behind for a corner.
James clears the initial corner but it is played back out to Tielemans whose cross fails to find a man in maroon to the ooos of the Leicester fans.
54 mins: Chance Chelsea! And we have the first shot on target of the game. Jorginho slots in Kante on the right channel. He finds Alonso at the back post but the Spaniard cannot direct his header either side of Schmeichel who saves.
52 mins: Chelsea win a free kick after Tielemans fouls Jorginho as Rodgers is seen giving James Maddison instructions on the sideline. Expect him to be introduced at some point.

47 mins: Iheanacho looks to bundle his way through a couple of Chelsea challenges but the Blues end up winning a throw in on the far side.
We are back under way!
Both managers have given the players their instructions and we are back under way for the second half at Wembley.
The rain has gone away and now the sun is out in London, So, who is going to step up and be the hero this afternoon?
HALF TIME: Chelsea 0-0 Leicester
The corner is belted away by Jamie Vardy and Oliver blows for half time. Neither side separated at the break after a cagey opening 45 minutes. Not a single shot on target from either side tells the story of the half! Tense.
45+1 min: Two minutes of added time, as Tielemans picks out Jamie Vardy with a cross but he glances wide.
45 mins: James' corner is overhit and goes behind for a goal kick. Werner looks to be in a bit of pain here but as half time approaches he will hope to make it to the break.
44 mins: Albrighton gives the ball away in his own half and Werner latches onto it. He drives at Fofana but he skews his shot wide, having taken a touch off Fofana. Chelsea corner.

35 mins: First booking of the game as Fofana goes into the book for a late challenge on Werner. It's not the first time a Leicester player has gone through the back of the German.
32 mins: Evans looks in trouble here. Rodgers wanted the 'brain' of his defence in his back three today but he doesn't appear to be fully recovered from a pre-existing injury. Terribly sad for the Northern Irishman as he limps off the pitch and waves to the Leicester fans.
30 mins: Huge chance Chelsea! Evans clears the initial corner but it is recycled by the Blues. The ball falls to Thiago Silva who crosses to Azpilicueta who is free at the back post but fails to direct the ball goalwards.
28 mins: Werner picks up the ball from Kante and drives at Leicester's retreating defence. With options left and right, the German shoots but blazes his effort over the bar. A waste.

18 mins: Evans gives a free kick away just beyond the half way line after going through the back of Timo Werner. The German has started brightly.

13 mins: Ziyech sends a ball into the box but it fails to find a Chelsea man and the ball runs out of play on the far side.
10 mins: Thomas releases Vardy down the left and it's game on between James and Vardy. The defender gets across to muscle his countryman off the ball. That is going to be a good battle.
8 mins: Another corner for Chelsea after Mount flicks the ball against Soyuncu's thigh and behind. Looks like James is playing as a right centre half today, perhaps to quell the threat of Vardy.
Ziyech's delivery is cleared at the back post, James sends it back in and Leicester clear once more.
6 mins: Chelsea enjoy a really nice spell of possession, moving it well in the Leicester half. Azpilicueta's cross is eventually blocked behind for a corner by Thomas.
Reece James' delivery is cleared with ease.
3 mins: Shaky start from Soyuncu, he takes a big swing at the ball but slices it horribly. Fortunately it falls into the direction of Luke Thomas who cleans up for the Turk.
Vardy now works his way down the left but his cross finds Kepa.
2 mins: Werner is again found on the right, this time by Ziyech, but his cross again fails to find a man in blue. Chelsea are definitely targeting Soyuncu's side of that back three.
1 min: Timo Werner is immediately unleashed down the right, he gets a ball into the box but it is directed straight at Kasper Schmeichel.
KICK OFF - THE FA CUP FINAL IS UNDER WAY!
All the pre-match formalities are done and all that's left is the football.
The players kneel in support of anti-racism, to muted boos, before Michael Oliver blows his whistle to get us under way.
Chelsea have donned their new snazzy home kit today, while Leicester are in their burgundy away strip.
The national anthem has been sung and all that's left now is for the pitch to be cleared before kick off.

22,500 fans are ready inside Wembley, after watching from afar for a year, what a special moment it is going to be for Chelsea and Leicester fans this afternoon.
Brendan Rodgers: Evans return a 'huge' boost
It’s a huge boost. Having that experience, that leadership quality on the field is very important, he organises the team on the field.
We were here for the semi final with 4,000 and that felt really nice but knowing that there are Leicester city supporters today is absolutely amazing. It’s great to see the supporters here.
The Leicester boss was speaking to BBC Sport.
How are the nerves, folks?
Just half an hour to go until kick off at Wembley, and the trepidation will surely be building among Chelsea and Leicester fans!

Cesar Azpilicueta: Extra special to have fans back
When you are a kid, especially knowing how traditional the FA Cup is in this country. It is a special day, with the fans back it is extra special.
Everyone that has experience has to help. It is massive opportunity, we are back in the FA Cup final and we have the Champions League final as well. It is a big opportunity and we have to be ready for it.
We have missed them a lot, it is extra special today to have them back and have this special atmosphere that is created in the FA Cup, hopefully we can share the joy after the game.
The Chelsea captain was talking to BBC Sport
Kasper Schmeichel: I have dreamt of this all my life
It's an amazing occasion, its something i have dreamt of all my life. The fans of Leicester will know how long it's been since we have been in a final like this and it's an amazing opportunity for us.
Being at Wembley and having fans after the year that we've all had is fantastic, hopefully it is a sign of things to come.
Everybody knows the connection the players have with the owners, they'll be here today supporting us like always. It is one of those situations where a win would mean a great deal to them and show that all the hours and investment they have put into us is worth it.
Schmeichel was talking to BBC Sport
Can Rodgers emulate Fergie this afternoon?
Victory for Brendan Rodgers' Foxes can see the Leicester boss emulate a feat previously achieved by Sir Alex Ferguson.
The Manchester United legend is the last manager to have won the Scottish Cup and the English FA Cup, something Rodgers can achieve this afternoon.
Tuchel makes FIVE changes, Evans comes in for Leicester
Thomas Tuchel makes five changes from the side that lost to Arsenal at Stamford Bridge on Wednesday night.
Antonio Ruidger replaces Kurt Zouma in the back three, Bill Gilmour makes way for N'Golo Kante in midfield.
Tuchel opts for the experience of Marcos Alonso at left wing back over Ben Chilwell, while Timo Werner and Hakim Ziyech replace Kai Havertz and Christian Pulisic up front.
For Leicester, Jonny Evans comes in for Marc Albrighton. Otherwise, the team is unchanged from the side that beat United in midweek.
Team news on its way in five minutes
Just five minutes until we discover how Chelsea and Leicester line up for this afternoon's final.
Thomas Tuchel bemoaned his vast changes after defeat by Arsenal, while Brendan Rodgers played a pretty strong team for Tuesday's victory at Old Trafford. So, how are each side going to line up? We'll find out shortly!
It could have been Ibiza! Vardy almost quit Leicester to move to party island
TOM COLLOMOSSE: Jamie Vardy revealed he came close to quitting and moving to Ibiza during his first season at Leicester.
Vardy will make history on Saturday when he becomes the first player to feature in every round of the FA Cup from the preliminary round to the final — 13 stages of the competition.
The 34-year-old aims to help Leicester win the Cup for the first time in their 137-year history and write another chapter of his remarkable story, after winning the Premier League title five years ago and securing the Golden Boot last year.
Thomas Tuchel loved the way Mason Mount took him to task over early selection snub... the midfielder has now become a player the Chelsea boss knows he can trust
ADRIAN KAJUMBA: When Thomas Tuchel announced the plans for his first game in charge as Chelsea head coach Mason Mount would have been forgiven for thinking ‘here we go again.’
The previous game Mount was on a high, Frank Lampard making him captain against Luton for what turned out to be the final game of his reign.
A few days later Mount was on the bench.
KEOWN TALKS TACTICS: Kante the key against his former club
MARTIN KEOWN: Thomas Tuchel knows how important N’Golo Kante is.
The midfielder with a twin engine loves a big occasion. He was man of the match in both legs of their Champions League semi-final with Real Madrid.
Chelsea’s second goal in their 2-0 home win over Real was down to Kante as he sprinted in anticipation of winning a second ball. He won possession, Mason Mount scored and Chelsea were confirmed as Champions League finalists.
From Waitrose to Wembley for Brendan Rodgers! Leicester’s boss aiming to land that big prize in England
IAN LADYMAN: Traditionally the FA Cup final has been about the journey. From first round to last. Up Wembley Way with the TV cameras on board. Then up the steps, hopefully to collect a winner’s medal.
This year’s version is a little different. The season is not yet over, for example.
Saturday’s finalists, Chelsea and Leicester City, meet again in the Premier League on Tuesday and that feels strange.
But some things do not change. Long roads have been walked by people like Jamie Vardy but Chelsea manager Thomas Tuchel has made it to Wembley seemingly on fast forward.
And then there is Brendan Rodgers. This is not his first Wembley final. He won the Championship play-offs there with Swansea in 2011. But an FA Cup final feels different and is different, the type of day that can remind people how far they have come.
THE NUMBERS GAME: Comparing Vardy and Werner ahead of the big game
Jamie Vardy and Timo Werner have endured a vastly contrasting week leading up to the FA Cup final, in a season in which the duo appear to have experienced rather different fortunes.
Vardy, 34, will have played in all 13 FA Cup rounds come Saturday and continues to demonstrate all the energy of a 28-year-old striker in the prime of his career in a side edging towards Champions League qualification after the win at Manchester United in midweek.
Meanwhile, German counterpart Werner has been on the end of yet more stinging criticism, with former Arsenal stars Ian Wright and Paul Merson both labelling him 'lazy', causing Chelsea boss Thomas Tuchel to launch a staunch defence of his compatriot.
We’re back at Wembley! Delighted fans arrive ahead of the Cup final
Delighted fans flocked to Wembley on Saturday with over 20,000 set to watch the FA Cup final between Leicester City and Chelsea.
Fans from Leicester who'd made the trip sported their team's blue colours, with some in fancy dress fox costumes in honour of the club's nickname.
Others sported silver tinfoil replicas of the FA Cup as they smiled for pictures while making the hallowed walk down Wembley Way. The on and off rain showers couldn't dampen the enthusiasm.
A Blue Riband event and blue ribbons on the Cup
It is always the showpiece occasion of the English football calendar and this year’s FA Cup final is just that little bit more special.
The fact 21,000 spectators will be inside Wembley today to watch Chelsea play Leicester City is hopefully a positive sign that life will soon be back to normal after the Covid-19 pandemic.
How fortunate those fans are to be here today to witness what should be an excellent final between two of the most impressive teams in the Premier League right now.
It’s a fifth FA Cup final in Leicester’s history - and a first since 1969 - and they’re still waiting for their first triumph.
Chelsea have had rather more success. They’re attempting to lift the trophy for the ninth time in their illustrious history.
Either way, we know blue ribbons will be on the famous trophy later on this evening.
Welcome along to our live coverage. There’s plenty of build-up for you ahead of the 5.15pm kick-off at the national stadium and full live commentary of the game.
