I'd say the feller has mental issues to do what he does in front of multiple cameras and the deny it happened.
I have been arguing this as well this week and have honestly come to the conclusion that people surely can't be as simplistic as they sound, it has to be they are looking for an angle to support their prejudice and that's just the news agencies, so this forum has no chance

South American football expert Tim Vickery
"This is an individual who has a self-control problem. You hope people around him will stop living in denial and help deal with the problem."
On the face of it seems a benign enough comment but I don't think he has a self control problem 'per se', in fact I think the evidence is there for all to see. He has stopped his diving, play acting, moaning (to a large extent), and generally got people on side last season. This has all taken more work than he is given credit for, change a career of one type of habitual action and replace it with a cleaned up version while still in super charged atmosphere at most grounds getting abuse and adulation in equal measure.
The biting thing seems to me to be something else, maybe akin to people who cut themselves or self harm, some bizarre mechanism to compromise yourself in order to mentally regain some control from a situation you think is getting away from you. There is never any logic to it so people who say he is such a cheat thinking he will get away with it with 30 cameras at every game are missing the point. In a rational moment he knows he will be spotted but all that logic disappears when that neurological reaction surfaces.
He seemed to actually make a direct beeline for Chiellini and it was all over in an instance followed by instantaneous recognition he was in trouble which makes me think if the consequences are so to the front of your thinking that they are immediately apparent as soon as you have committed the act, what was it that over-road them and made you do it? He still nees help, obviously not the finished articular but not so bad to justify the hyperbole.
Separately while I have taken the trouble to type something (for a change) this was also in the same article:
Former Chelsea winger Pat Nevin
"The ban could have been longer. I was guessing six months. Liverpool is a fabulous club, it is a proud club and it does not need someone doing what he has done.
"There are lots of hints about Barcelona and Real Madrid being interested in him before this incident and it probably makes it easier for a move to happen. Football
does not have morality when it comes to these kinds of matters.
If they were interested in him and decided against a move because of this, I would be astounded."
So if there are no morals that would prevent a big club with huge history buying him, why would our club feel the need to get rid? Could understand it if he had a red shirt on at the time of this latest indiscretion but he was in the blue of Uruguay. Why are these "experts" so one dimensional in their analysis.
