Roy Keane says Marcus Rashford has developed 'bad habits' at Man Utd during in-depth analysis

Roy Keane has claimed that Marcus Rashford has developed 'bad habits' in his style of play at Manchester United after the side's FA Cup win over Wigan.

United secured a 2-0 win over the League One side at the DW Stadium to progress to the FA Cup fourth round, with goals from Diogo Dalot and Bruno Fernandes.

They will now face either Newport County of League Two or Eastleigh of the National League in the next round.

Rashford started the game and assisted Dalot's opener, and had four shots on goal before being replaced by youngster Omari Forson in injury time.

It has been a challenging season for the England star, who has scored just three goals in all competitions for his club.

And speaking on ITV after the Wigan victory, Keane detailed where he believes things have gone wrong for the 26-year-old this term.

He explained: "I just wanted a bit more [today]. I have high expectations of Rashford - I always want a bit more. He's played a game here, getting shots away.

"He's got I think one or two bad habits, where he's stopping the ball and trying the flicks at the wrong time. I don't think he runs in behind enough.

"I think we were getting frustrated watching him, I think United fans were frustrated watching him.

"United were playing against a League One side here, and I think Marcus must walk off the pitch thinking, 'For all these opportunities, I should be scoring, or certainly providing more assists'.

"That might sound a bit harsh, but that's because we expect a lot from him. It's just these little details.

"He's gone into the habit as well of stopping the ball dead, that makes it easier to defend.

"Listen, one or two shots can go wide, don't get me wrong. Just overall - yeah, we're quick to criticise body language, but there were parts of his game tonight that just frustrated me, and I hope they frustrated his team-mates as well, and they should be saying, 'Listen, we expect more from you'."
