Former Arsenal star Paul Merson believes Manchester United must beat Southampton this weekend or they will be out of the title race.
David Moyes' side have had a tricky start to the season, having won just three of their opening seven Premier League fixtures.
United currently find themselves in ninth place in the table, behind new-boys Hull City and will be desperate to make it back-to-back wins after beating Sunderland last time out.
If United do fail to beat Mauricio Pochettino's side they could find themselves up to nine points behind the leaders after the weekend's play.
And, writing on his Sky Sports column, the pundit has insisted that the Red Devils must beat the high flying Saints on Saturday.
Merson said: "This is a big game for Man United - and I mean massive. If they don't win this then they can't win the Premier League, it's as simple as that.
"David Moyes has said they had a hard start and their early run of games wasn't fair, but they lost to West Brom and fell over the line against Sunderland - I thought they were lucky in that match - and now they need to beat a Southampton side that is playing well."
But Merson has admitted that he expects Moyes' side to secure victory this weekend.
He continued by saying: "However, I've got to go for Man United at home."
Do you agree with Merson? If United fail to beat Southampton, will they be out of the title race already?
