Manchester United beat Stoke City 2-1 at Old Trafford to secure their fourth consecutive Premier League victory.

But they were made to sweat for it as Mame Biram Diouf, a former Red Devil, saw two efforts cleared away on the line in stoppage time.

Juan Mata's second-half free-kick evaded everybody and flew into the corner to help the hosts earn the spoils after Steven N'Zonzi had cancelled out Marouane Fellaini's header at Old Trafford.
