Former Premier League ref Graham Poll says Manchester City were robbed a penalty in defeat to Manchester United.

Poll wrote for the Daily Mail: "Manchester City should have won this contest, not just due to the numerous missed opportunities in the first half but because after 77 minutes they should have had a penalty and faced 10 opponents.

"Referees never want their performances to affect the outcome of a match but Martin Atkinson will be hard pressed to say that when watching the game back.

"How he and his assistant failed to award a penalty is beyond me.

"Manchester United's Ashley Young flew into a tackle at pace, with both feet off the ground with studs up. That makes it a foul irrespective of its outcome."
