Manchester United have confirmed that Luke Shaw has suffered a double leg break.

The United left-back left the field on a stretcher after suffering a serious injury in the first half of their 2-1 defeat to PSV Eindhoven on Tuesday evening.

The Red Devils tweeted that initial fears had been confirmed and Shaw is now set for a lengthy spell on the sidelines once he has undergone surgery.

The club's official account tweeted: "Our thoughts go out to @LukeShaw23, who has suffered a double fracture of the leg. He will have an operation on his return to Manchester."

Shaw moved to United from Sunday's opponents Southampton for around £27m in the summer of 2014.
