Easily one of the best shot stoppers and at a stupidly young age, his ability in the air still needs a huge amount of work though.
He's not physical enough to push past players, doesn't look remotely comfortable catching those high balls and gets lost on crosses.
All things no doubt he's working hard on though and with his young age you'd expect him to be able to sort out at least two of those three issues(He'll never be physical enough IMO). FM Nutter brings up a good point though, will he still be at United once he's sorted them?
