Marouane Fellaini’s stoppage-time header gave Manchester United a 2-1 victory over Arsenal, denying Arsene Wenger a point on his final visit to Old Trafford as the Gunners manager.
United had taken the lead on 16 minutes when Paul Pogba volleyed home from close range after Alexis Sanchez had headed against the post.
But Arsenal responded well and former United midfielder Henrikh Mkhitaryan went close before equalising six minutes into the second half with a drive into the bottom corner.
United piled on the pressure and after Marcus Rashford’s goal was ruled out for offside, Fellaini headed in with the back of his head to seal victory.
Second-placed Man Utd are now five clear of Liverpool in third and are guaranteed a place in the top four while Arsenal remain in sixth, three ahead of Burnley, who played one more match.
