Suarez is a very fine player, but a complete idiot. I admire the way he hassles defenders, but he is ready to implode at any moment. Apart from the incident in question his career is littered with nasty incidents which include eye gouging, biting, diving, abusing and fighting other players (including his own team mates) and a couple of horrible tackles. He made his comeback against Spurs and kicked (deliberately) Parker in the stomach within 5 minutes of being on the park. It is natural to defend your own, but outside of Liverpool very few people think he was the innocent party in the Evra affair, that amounts to one massive conspiracy.
He is an accident waiting to happen and it won't be long before he blots his copybook again or cops some retribution from one of the players he winds up. This comment proves he has learned nothing from the experience he went through. He is basically calling those involved liars. In the circumstances only a fool would do that, the kind of fool who tells his manager he will do one thing and does the other.
