Amad Diallo was seen on crutches after Manchester United's preseason win against Arsenal.

Amad was a halftime substitute, but lasted only ten minutes.

The winger broke down with an ankle injury and was taken off via a medical buggy.

He was later seen on crutches with early reports suggesting Amad has suffered a twisted ankle. Strapping was delivered to his ankle.

United's youngsters face Wrexham in San Diego on Tuesday before the senior team play Real Madrid in Houston on Wednesday.
