United, which lost Anthony Martial in the warm-up following a leg injury, scored the only goal at Carrow Road in the 72nd minute when Juan Mata drove in a near-post finish from Wayne Rooney's assist.

United remains in fifth place but is now just one point behind rival Manchester City, which hosts third-placed Arsenal tomorrow.

Norwich was unable to make any real impact in the match and remains 19th on 31 points with two games left.
