Point 1 - In that instance, a lot of players have a nasty side, including ones that are highly regarded in world football. The odd instance in which a bad tackle is made does not incur a nasty side to a player.
Disagree entirely. He went in to hurt the guy. Don't let your bias blind you.
Point 2 - As a Norwich fan, I'd assume you don't really watch much of Newcastle's games? As in that case you'd know tackles like that are few and far between, throughout his whole career. Regarding the picture, if that was someone like, say Scholes, it would be described as committed and that he couldn't pull out. Nasty challenge, no denying it, but how it is regarded generally differs from player to player. It has no reflection on his personality at all as he is not a dirty player, may whine a bit recently, but not dirty.
I'm not a Norwich fan - The name has absolutely nothing to do with football. I've watched almost every game Newcastle have played this season, and I've seen Cabaye put in more than his fair share of dirty tackles.
I'm not saying the guy should be strung up or anything, I'd just like to see people acknowledge that he's not this clean cut pretty boy that you want him to be.
