The difference between Suarez and the others is exactly what Jess said - it's the third time. There's also the fact that everything he does, he denies like a coward. Did De Jong or Zidane deny what they did? No, they said stuff like "he insulted my sister, and I honour her, so I floored the smurfer." Luis is all "waaahhhhh, I would never bite someone, not once, not twice, not three times, this is all a big misunderstanding, I'm also not racist, my teammates are black and I never bit them once I didn't."At least when he handballed he admitted it.
Overall the guy is just a dick cheat player. At least when Ronaldo dived, whined or moaned United players were capable of saying he should man up and get on with things. Liverpool are too precious about their little schnookums. I'm not sure if it's sort of like a mum and dad wanting to protect their wee baby by covering him in cotton balls, or if it's sort of like a mum and dad not saying anything because they live in fear that he will eat them for doing so.
Either nothing will happen or Suarez will get a suspension for like 6-10 games sometime after the World Cup. Nobody in the big top has the guts to get rid of a PL player for years in this day and age.
