Alexis Sanchez will feature for Manchester United against former club Arsenal in the FA Cup fourth round, but goalkeeper David De Gea is set to be rested.

Sanchez has not played since the third round after sustaining a hamstring issue, while Marcos Rojo and Marouane Fellaini remain sidelined for Friday’s game.

Chris Smalling has returned to training after a foot complaint, although Ole Gunnar Solskjaer does not plan to use him on Friday, but Luke Shaw is back from illness. De Gea was not seen with the squad as they made their way to London, nor was Antonio Valencia, Scott McTominay or Matteo Darmian.

Provisional squad: Romero, Grant, J Pereira, Dalot, Shaw, Young, Jones, Bailly, Lindelof, Fred, Matic, Herrera, A Pereira, Pogba, Lingard, Mata, Sanchez, Martial, Lukaku, Rashford.
