Manchester United team news: Antonio Valencia will not play against Young Boys

"Valencia's situation, we need to protect his clinical situation, apart from that we go with everything we have and have to try and win.

"So, we brought Luke Shaw back to the squad and to the team.

"I told already Luke Shaw is playing and apart from him we have Diogo, Ashley Young and Darmian ready to play."

Mourinho, however, insists he will not use Young Boys' pitch as an excuse.

"I don't want to use the pitch, especially before the match, as a possible excuse for a not very good performance," he added.

Marcus Rashford is line to start, meanwhile, with the striker set to accompany Romelu Lukaku in attack.

Probable Manchester United starting line-up:

De Gea, Darmian, Smalling, Lindelof, Shaw, Matic, Fellaini, Pogba, Mata, Lukaku, Rashford.
