David Silva feels Manchester United's late winner at Manchester City was the difference this season.
Silva feels City have played well but have never been able to claw back the deficit after losing to a late United goal at the Etihad Stadium last December.
He said: "I feel I have had a good season like all my team-mates - I think the difference has been that goal.
"But we still have the FA Cup and I think we can win that."
