With all due respect, but you have got to be kidding me right?
Wenger is without a doubt the sorest loser of the lot. He very rarely pays a complement to the opposing team even when his team has just been played off the park (the match against Barca is an exeption to the rule, believe me).
There's a reason why a lot of other PL managers don't like him, he doesn't respect or acknowledge the other team when Arsenal get beaten.
Fergie rants a lot but it's usually directed at officials, the FA etc. When Utd lose more often than not Fergie will complement the other team and that's why he's respected by the majority of the managers out there.
Btw, I thought his comment after the game was stupid, but going out of Europe after being 3-0 up I'll put it down to extreme dissappointment.
