The two clubs have historically battled each other for supremacy at the top of the English game for decades, while this term they are in direct competition for the Premier League trophy.
Liverpool’s recent rise to prominence has added extra spice to the rivalry, with the Reds’ maiden Premier League crown their 19th in top-flight history, drawing them to within one of United’s all-time record.
The Red Devils are more emphatically ahead in the FA Cup stakes, having lifted the trophy on 12 occasions to the seven of the Anfield club.

This is a rivalry that dates back over 100 years, when the current iteration of the clubs met in an FA Cup first-round match on 7th February 1903. Manchester United ran out 2-1 winners at their Bank Street home.
Technically, the history of the tie goes back to 1898, with Newton Heath, as United were known then, beaten 2-1 in a replay in a second-round match following a scoreless draw.
Since then, the clubs have clocked horns in the fourth round on four occasions. United had been undefeated in those fixtures since going down 2-1 to Liverpool at Anfield in 2012. That was also the last time they met in the cup.
Indeed, United have been the dominant force of the rivalry, winning nine times compared to Liverpool’s three.
Included in the Red Devils’ victories are the only two occasions they have previously met in the final.
The 1977 showpiece saw goals from Stuart Pearson and James Greenhoff give Tommy Docherty’s side a 2-1 win in front of close to 100,000 at Wembley.
It was 19 years later before the fixture was repeated, with an Eric Cantona strike enough to settle the 1996 final in the Old Trafford’s side favour.
