Amad Diallo wing-back dilemma exposes the limitations of Ruben Amorim’s controversial Man Utd formation

But Ferdinand also admitted that Amad was not being used in his best role by Amorim: “Would he be better as a right winger? I think he would be, but that’s not detracting away from what he’s doing. I think he’s just what this team need in this position right now.”

Amad’s defensive weaknesses are not the only drawback with United playing wing-backs. While the ex-Atalanta youngster is not suited to the defensive responsibilities that come with the role, the player on the other flank, Dalot, is not made for its attacking demands.

“Amad’s been getting questioned but as a wing-back, you’re asked to be a full-back defensively, so Amad’s asked to be here and defend crosses at the back post. But then when he gets up here, he’s asked to be a winger,” said former Liverpool defender Jamie Carragher on Sky Sports’ ‘Monday Night Football’. “Now he is more of a winger, he’s probably more suited to that position, but then Dalot’s the opposite, where he may be able to deal with that [defensive headers] better. But when he gets on the last line and they actually get the ball to Dalot, he can’t beat a man.

“He’s not going to play a clever pass, he’s not going to get a cross in. So for me, that’s a little bit of a downfall in terms of getting five on the last line. It’s whether these players have the quality.”
