Leicester City coach Claudio Ranieri believes his side would have Beaten Arsenal had they not been reduced to 10-men following the dismissal of Danny Simpson.
The Premier League leaders took the lead on the stroke of half time after Jamie Vardy won and converted a penalty, but a second bookable offence for Simpson - fouling Olivier Giroud - changed the game.
Marcin Wasilewski was then punished for conceding a free-kick against Nacho Monreal in stoppage time, as Danny Welbeck converted Mesut Ozil's delivery in his first appearance since April 2015.
And Ranieri feels his side threw away the three points after costly individual errors saw them slip to a 2-1 defeat in a vital fixture in the race for the Premier League title.
He told reporters:
"Fantastic match, very fast. 11 versus 11 I think we win. Both yellows for Simpson were fouls, but not yellows. Why send him off?
"Arsenal are a fantastic team, but we were in control. They were smarter than us for the winning goal.
"We played to win and played well. We lost, so well done to our opponents. We're still top. We're focused on Norwich."
The Gunners are now just two points behind league-leaders Leicester in the race for the title with 12 games to play.
