Arsenal boss Arsene Wenger says defeat to Wigan Athletic shows the strength of the Premier League.

Wigan stunned the Gunners 2-1 at Emirates last night.

"Everyone is in the same situation. You could see with Tottenham against Norwich, Manchester United at Wigan, us against Wigan," Wenger told arsenal.com. "You have to realise that every game is a decisive moment for everybody. You have to be prepared not to be 1-0 down, to be 2-0 down, not like that. When you see the goals we conceded recently, we did not concede these kinds of mistakes."
