Manchester United icon Lee Sharpe has laid into one of the club's star forwards.

Sharpe, who has always been outspoken, criticized Marcus Rashford's performance in the FA Cup against Wigan Athletic on Monday night.

United won the game 2-0 to progress to the fourth round, but Rashford did miss several opportunities to turn chances into goals.

Sharpe told The Sun on behalf of Fruityslots.com: "Last season, he was unbelievable.

"He was sort of a shining light when the manager came in and this season he doesn't quite seem to have got up to pace.

"I don't know whether it's a confidence thing, whether he's got something going on off the pitch that's concerned him a little bit. But he doesn't seem as focused as direct.

"I watched him last night and you know, after four or five minutes he touched the ball three or four times and not once did he sprint at the full-back or sprint in the game and [after] his first touch he stood someone up and tried to do a trick.

"And the guy's tackled him [to send the ball out for a] throw in and Marcus Rashford just turn around and just stroll to get the ball and you're thinking you know, [it's] an FA Cup tie away at Wigan.

"The fans are going to be up there, the team will be up for it, Man United need to impose themselves, they need to play quick, they need to play with some authority. And just to walk towards the ball...

"You want them to declare intent and tend to show purpose and just to walk off the pitch… I don't think lazy is the right word....

"I don't know whether it was a bit of arrogance or whether he's lacking in confidence or what it is, but he just doesn't seem to be going past players.

"He seems to be second-guessing himself at times when he's squared up two players. He's an unbelievable player with so much ability."
