Manchester United had considerable worries in terms of their defence ahead of Wednesday's Premier League home clash with Arsenal.

United boss Jose Mourinho said on Tuesday morning that Phil Jones, Chris Smalling (foot), Eric Bailly and Antonio Valencia were not looking ready to play. Ashley Young (suspension) and Victor Lindelof (muscular injury) will definitely miss out, and while Matteo Darmian is able to return, Luke Shaw is a doubt after coming off with a knock in Saturday's 2-2 draw at Southampton.

Two others taken off at St Mary's were forwards Romelu Lukaku (knock) and Marcus Rashford, and there is a question mark over the former, while the latter was backed after the game by Mourinho to be fit for this contest. Alexis Sanchez (hamstring) remains sidelined.

Provisional squad: De Gea, Romero, Rojo, Dalot, Shaw, Darmian, Pogba, Mata, Lingard, Pereira, Fred, Herrera, Fellaini, Matic, McTominay, Lukaku, Rashford, Martial
