Man Utd suffer huge injury blow as winger struggles to walk after being subbed off just 13 minutes after coming on

MANCHESTER UNITED are sweating on Amad Diallo after the sub winger struggled to even walk after being forced off injured against Arsenal.

The former Sunderland loan sensation, 21, lasted just 13 minutes during the second half of Saturday’s friendly in the MetLife Stadium, New Jersey.

Amad Diallo was crocked as he bids to earn a first-team spot this seasonRex

Uruguayan Facundo Pellistri came on for Diallo just before the hour mark.

Bruno Fernandes and Jadon Sancho had struck fiercely-driven goals late in the first half to put United 2-0 up.

And the Red Devils’ high-tempo style impressed after the break – until Diallo’s injury and the inevitable batch of substitutions.

The four-cap Ivorian, was helped along the touchline as he limped away following his substitution.

He appeared ultra careful not to put pressure on his left foot.

Diallo’s blow will be especially disappointing to the ex-Atalanta starlet as he attempts to finally break through for United.

A clutch of clubs were keen on his services after he nearly fired Sunderland to promotion from the Championship.

Instead it was another wideman – under-pressure Sancho – who literally took his chance to press for a regular starting role.

Fernandes cut in from the right to fizz home a 20-yard left-footer on the half-hour that the diving Aaron Ramsey perhaps should have kept out.

And seven minutes later Sancho punished dozy defending by Gabriel when he burst into the right of the box for a top-corner finish.
