You can see highlights of Manchester United v Liverpool on Match of the Day 2 at 22:00 GMT on Sunday on BBC Two and the BBC Sport website.
Sunday's game at Old Trafford is arguably more important for Manchester United because, if they beat Liverpool, their momentum grows and the gap between them and the top four gets even smaller.
Jose Mourinho's side will be full of confidence too. They are on a nine game-winning run, look strong and powerful and all their big players have been performing very well for the last couple of months.
