4 things we learned from Manchester United's FA Cup win over Wolverhampton Wanderers

#3 Rashford injury might mean dreadful spell for United

Marcus Rashford had a knock to his back which forced him to go off

One of the few positives of Manchester United's season has been the coming of age of Marcus Rashford. He has stepped up in the big games and his 19 goals and 5 assists in all competitions show us that he has been the focal point of United's attack for a long while now.

He came onto the pitch at the 64th minute mark and went into a challenge with Matt Doherty where he came out second best clutching his lower back.

Never want to feel like I’ve let my teammates, the club and most importantly the fans down so did my very best to carry on tonight and was gutted to come off.Top work from the lads to get into the next round 👊🏿 pic.twitter.com/ZLpxiqhtq3

His immediate withdrawal and subsequent comments by his manager in the post match presser mean that he might be out for a spell where United simply can't afford to miss him with Liverpool, City and a return of Wolves on the horizon. Solskjaer said,

"He’s getting treatment now and hopefully we can get him back for Sunday but I’m not sure.He’s struggled with his back lately and he’s got another one.That backfired a little bit. Yes we got the goal and he was involved in the goal but it might have cost him Sunday.”

He was quick to add,

“He’s a quick healer and he’ll play through some pain, definitely, if he’s capable and it’s not a bad, bad injury, but we’ve seen that he’s struggled lately."
