Chelsea moved to the top of the Premier League after coming from behind to beat Leeds 3-1 in an entertaining encounter.
Just four minutes were on the clock when Patrick Bamford struck to give Leeds the advantage and silence the 2,000 home fans.
But they were much happier when Olivier Giroud equalised after instinctively poking home from a superb Reece James cross.
On the hour mark Kurt Zouma headed home from a corner for his fourth goal of the season to put the Blues ahead.
And Christian Pulisic converted Timo Werner's cross in injury time to seal the victory.
Here are five talking points from Stamford Bridge...
Lampard's entertainers are real contenders
Make no mistake about it: Chelsea are well and truly in this title race.
There may have been some question marks about them defensively initially this season, especially after they conceded three in draws against both West Brom and Southampton.
But the fact of the matter is that they have such an enormous amount of firepower going forward that they can outscore anyone.
Giroud and Pulisic's goals mean they have now amazingly had 13 different scorers in the Premier League so far in the current campaign.
And when they are in full flow there are not many that can stop them, with even Marcelo Bielsa's highly organised troops powerless at times tonight.
They may not remain on the top of the table by the end of the weekend, but it would take a brave person to bet against Chelsea finishing first at the end of the season at this rate.
Giroud does it again
Never, ever write off Olivier Giroud.
The evergreen 34-year-old was widely expected to leave in the summer, but his sensational four goals in the Champions League against Sevilla on Wednesday meant Lampard had little choice but to start him tonight.
And he provided a typical front-post finish to equalise, with the goal his sixth in a row when starting for the Blues.
The way he is playing at the moment, he is becoming almost impossible to drop even with Tammy Abraham and Timo Werner available.
Giroud is, quite simply, ageing like a vintage French wine.
Havertz flatters to deceive once more
When are we going to see the best of Kai Havertz?
Chelsea's record signing has got off to a slow start since joining from Bayer Leverkusen for an initial £62m.
And he was off the pace again tonight, looking slow in possession and some way off the electrifying, dazzling player we saw in the Bundesliga last season.
While he is not the only player to struggle to adapt to English football after a big transfer, Blues fans no doubt expected much more, and Lampard still seems unsure as to how to unlock Havertz's potential.
The best is surely yet to come, but tonight was another underwhelming display before he was hauled off on 66 minutes.
Timo Werner could have had a hat-trick on another night.
Instead he somehow ended up with zero goals after missing a whole host of good chances.
His worst offence came early on after he inexplicably failed to turn home Giroud's flick on from a corner at the back post.
But he also wasted two or three more really good opportunities, and will be livid with himself for not bagging at least one.
The positives are that he still looked lively and got himself in decent positions all night, also managing to grab an assist late on, and it should just go down as one of those evenings rather than a reason to panic.
Bamford haunts the Blues
Bamford was back at Chelsea with a point to prove after failing to make a competitive senior appearance for the Blues despite being on their books for five years between 2012-17.
And it didn't take him for him to finally, belatedly, make his mark at Stamford Bridge, slotting home well to open the scoring after Kalvin Phillips had set him free.
The goal was Bamford's eighth in the Premier League so far, with seven of those coming in away games, and he is certainly confounding those who didn't think he would ever make it in the top tier.
It is just a shame for him that England are blessed with so many talented forwards at the moment, otherwise he could have been making a late bid to be involved in Gareth Southgate's squad for the Euros.
