Manchester United are through to the fourth round of the Carabao Cup - by the skin of their teeth.

A staring XI containing the likes of Paul Pogba, Fred and Jesse Lingard needed penalties to overcome League One side Rochdale in yet another worrying performance by Ole Gunnar Solskjaer’s side.

It came just days after a lacklustre display against West Ham which resulted in a 2-0 defeat.

There’s very little to be happy about right now for United fans.

But there is one positive that came out of the tie against Rochdale.

17-year-old Mason Greenwood scored his second goal in a week at Old Trafford after he notched the only goal of the game during United’s 1-0 Europa League victory against Astana.

And it produced a rather staggering statistic.

That’s because Greenwood has now scored more goals for United in open play in the past week than Marcus Rashford has managed in almost six months.

Astonishing.

Greenwood is making it almost impossible for Solskjaer to drop him ahead of next Monday’s Premier League clash against Arsenal.

One thing is for sure, his manager rates him very highly - describing Greenwood as one of the ‘best finishers he’s ever seen.’

“He’s still very young but he’s been maturing in the last six months,” the United manager said.

“When I first came here I found a kid who just wanted to play with his mates in the under-18s, but now he’s knocking on the first-team door and his appetite is growing. I don’t want to put too much pressure on him at this stage, I just want him to go out there and enjoy himself.

"He’ll be all right when the ball lands at his feet because he’s one of the best finishers I’ve seen, but the game is all about working hard and closing down when you don’t have the ball.

“Finishing might look as if it comes naturally to Mason, but I don’t actually believe you get gifts like that from birth and I’ve seen how hard he works in training. His technique is brilliant, and that is a result of constant practice and repetition.”
