There's a lot of hypocrisy among some Arsenal fans regarding Luis Suarez's behavior. I can't defend him on the alleged racist words he said to Evra. All I know is that Evra is not exactly a saint.
What pisses me off is when I hear some Arsenal fans complaining about Suarez's diving, the Ivanovic bite or that deliberately tries to injure other players etc.
Patrick Vieira is an Arsenal legend and one of the dirtiest players in Premier League history. I remember that he was banned for spitting Neil Ruddock. Spitting is infinitely worse than biting someone's hand, it's not even close. Is the most despicable reaction you can have, is beyond vile. Fabregas was also accused of spitting Ballack and Hull City's assistant coach. I don't even want to start enumerating Vieira's reckless tackles, there were many of them.
