But Mancini said: "Last year Chelsea won it and this year English football has three teams in the quarter-finals of the Europa League.
"For three or four years English teams have won, or been to the final. For one year, other teams have done it.
"When I read this thing about English football being down I thought it was stupid.
"It is impossible to win every year. This reaction is like Italy where if you win one game you are the best team and if you don't it is a disaster.
"This is football. If every year the same teams win, football would be like other things.
"Football is good for this. Every year things can change."
Is Mancini right about Wenger's comments being "stupid"? Or is Wenger right? Give us your shout below...
