Paul Merson has told SkySports he expects Manchester United to beat rivals Liverpool this weekend.
The Red Devils are in fine form coming into the game, having won their last nine games in all competitions.
Liverpool are coming off a midweek defeat in the EFL Cup in which they failed to score, and were fortunate to lose by only one goal.

Merson picked out James Milner as the Liverpool player Manchester United can exploit at Old Trafford on Sunday, believing him to be a weak link.
He said: "Defensively they were all over the place at Southampton and James Milner could have a long day against Marcus Rashford or Anthony Martial."
Milner has been playing at left-back this season and has done well, but the pace of Rashford or Martial could well trouble him.

Martial scored on his debut in the corresponding fixture last season and would love to have the same sort of impact again.
Merson is predicting a 2-1 win for Manchester United, but warns their season could hinge on the result of the match.
He added: "I think they [United] are big players if they win this match, but if they lose then you are looking at whether they will get in the top four."
