Manchester United new boy Anthony Martial picked up an injury against England.

Manchester United striker Anthony Martial has left Wembley on crutches after France's international fixture against England.

Martial started the game, and saw club teammate Wayne Rooney score as England won 2-0.

He played 66 minutes in the match at Wembley, before being substituted for Atletico Madrid's Antoine Griezmann.

The extent of the injury to Martial is currently unclear, but the French medical team are clearly taking every possible precaution, and Manchester United will assess him upon his return to the club.

United face Watford at Vicarage Road in the early game on Saturday, meaning Martial has little time to recover if he is nursing a knock.

He had provided a stunning assist for Olivier Giroud in France's win over Germany on Friday, and has been an outstanding performer for United so far this season, living up to his big price tag since his move from Monaco.

The one positive for United is that Wayne Rooney showed his scoring touch, and the Red Devils will need him to step up this weekend.
