Manchester United have confirmed that center back Lisandro Martinez has suffered an ACL injury. MORE — Man United vs Crystal Palace recap Martinez was stretchered off the Old Trafford pitch in tears after suffering the injury in the 2-0 defeat against Crystal Palace on Sunday.

Amorim could mix things up further by moving the Dutchman to the central centre-back position and Maguire to the left. Maguire has experience playing as the left-sided defender in a three for England and Hull City but he is more of a ball-carrying centre-back than a passer.

Manchester United will be looking to book their place in the fifth round of the FA Cup tonight. United face Leicester City in the fourth round of a competition they won last season. Ruud van Nistelrooy is set to return to Old Trafford with Foxes following his spell in interim charge of United prior to Ruben Amorim's appointment.
