Liverpool paid two visits to Old Trafford in 2020/21 and the matches certainly didn’t lack for excitement with 11 goals scored across the 180 minutes.

Having been knocked out of the FA Cup thanks to a 3-2 defeat in January, the visitors avenged that loss with a 4-2 victory in May.

While some of his side’s defending will have dismayed Jurgen Klopp, none of his senior centre-backs featured in either game. Whomever he selects on Sunday, Liverpool should have a much sturdier foundation at the back for the forthcoming encounter.

And there was plenty that the Reds’ boss would have enjoyed about his team’s goals in the red half of Manchester last season, which they can look to repeat this weekend.

Liverpool opened the scoring in the cup fixture through Mohamed Salah, and though his finish was customarily excellent, this was one goal for the Egyptian where the assist was arguably more impressive.

As the visitors brought the ball out from the back, United were very clearly defending in two banks of four. Yet Roberto Firmino was able to play a pass through both lines which put Salah clean through on goal.

Liverpool have already picked up four through ball assists in the league this season, which is the joint-most by any team from England, France, Germany, Italy and Spain, and Divock Origi also added one against AC Milan, so the Reds are in great form on this front.

The second goal in that cup defeat was classic Klopp football too. As United looked to play out from the back following a goal kick, Salah put Harry Maguire under pressure.

While the United captain was able to evade the press and play the ball forward to Edinson Cavani, the Uruguayan’s subsequent pass was seized upon by James Milner. He drove forward, played the ball to Firmino and he in turn found Salah who scored. From a goal kick to the back of the Stretford End net in approximately 14 seconds.

Something similar occurred at the opposite end of Old Trafford when Liverpool returned for the league game in May.

Once again United looked to play out from their six-yard box, and again a wayward pass – by Fred on this occasion – was picked up by Trent Alexander-Arnold. Initially, it looked as if the home side had got away with their error as the right-back couldn’t find a colleague in the box, but as Luke Shaw looked to move forward, he was crowded out by two Liverpool players and the ball broke to Firmino.

His pass to Alexander-Arnold enabled the number 66 to have a shot on target, and though it was saved, Firmino poked home the rebound.

Klopp’s team have been the masters of final third pressing over the last four years – only Napoli from the big leagues have made more pressures in the attacking third since the start of 2017/18 – and they put this ability to devastating effect in Manchester twice last season.

When Firmino scored that goal, Liverpool were already 2-1 up thanks to another of their very apparent strengths: set piece goals.

The first came after a period of penalty box pinball which was brought about by United failing to clear a corner, with Jota eventually flicking home a shot from Nat Phillips. Thirteen minutes later, Firmino found space at the back post to head in a free-kick delivered by Alexander-Arnold.

And Liverpool’s final goal that night closed the circle on their two matches at Old Trafford, as it was created via a through ball just as the first in the cup clash had been. Not only that but it was an Opta-defined counter attack, of which the Reds have scored more than any other Premier League team since the start of 2016/17.

The goal’s final point of interest stems from the identity of the assist provider and the distance that his pass travelled. Liverpool have had seven long ball assists in league and Europe since the start of last season, and Curtis Jones has been the creator for four of them, including for the goal which capped a famous victory at United.

With full knowledge of what the young midfielder is capable, Klopp will have his fingers crossed that Jones will be fit enough to play on Sunday.

Indeed, Jones sat out of Liverpool's trip to Atletico Madrid and the Reds will be hoping the extra rest is sufficient to see him recover for the Premier League showdown.

He said: "Unfortunately, Curtis was only with us in the warm-up and will be here in Liverpool to hopefully make the final steps to full training.

“Today he only warmed up then did his stuff.

“Still individual training, we decided to leave him here to continue that. Then hopefully he’s ready for United.”

With his long-range creativity, Liverpool’s pressing in the final third and their decent form with set pieces, the Reds can look to repeat their goals from last season in order to bring home three points from Old Trafford once again.
