Former England coach Sam Allardyce believes Manchester United will struggle to finish in the top four this season.

Jose Mourinho's men currently sit seventh in the table with 10 points from their first six league games.

“I think that at the moment the one of the top six that has the biggest worry at the moment is probably Man United," he told talkSPORT.

“I wouldn't like to say at the moment but it's going to be a struggle if they're not careful to finish in the top four.

“I think that's going to be devastating for Man United and Jose, but it's still a bit early to tell.

“There were signs they were on the right track, they had a comfortable win in Europe.

“But maybe that European game has affected some of the players on Saturday.

“Maybe that was the real key element that Manchester United underperformed.

“Manchester United have always been able to cope with that situation but maybe they didn't cope with it so well.

“It's always a good time to play against a team when they come back from Europe, whether it's the Europa League or Champions League."
