So, Neymar is out of the World Cup. It has been reported that he has fractured his vertebrae in his lower spine after being kneed in the back by Juan Zuniga in a challenge that went unpunished. I have had an opportunity to review that challenge many times and at many different angles and I all I can say is: What was Zuniga doing? It is an incredibly poor, nasty  challenge that should have been severly punished. There needs to be more vigilance to protect players with ability like Neymar. He is a valuable asset and it shouldn’t be down to foolish incidents like this to take him out of the game. Football is a physical sport and I believe it should remain so, but there is no room in the game for such a challenge.But now this presents an even bigger problem for Zuniga; hours after the incident there were a series of unacceptable racist death threats sent to him. I feel no need to repeat some of these vile slurs, but I assure you that some of the messages that have been posted are utterly horrendous. It is at times like this where football can bring out the worst in people. Just as there is no room in the game for sloppy, dangerous challenges – there needs to be equally zero tolerance of small-minded, discriminatory statements.Although Neymar has been ruled out of the World Cup after fracturing his vertebrae, the examination has shown that he does not require surgery. The Team Doctor, Rodrigo Lasmar, has stated that he would only need immobilisation to recover. This is a blessing. This ugly incident can hopefully be forgotten without any lasting impact on Brazil’s star player.The question we need to ask ourselves is what will Brazil do now? How will they respond to losing their key striker? Tragedy often spawns victory, and this could in fact spur them on to win the World Cup – the players now have the chance to come together and fight back in unity. But they will be shaken. Their poster-boy is down and out; their foundation is unstable. But all this uncertainty just breeds more excitement. There is no doubt in my mind that there will more twists and turns and exciting moments in the next week with the World Cup. As Wimbledon rolls around I have been thinking back to the greatness of John McEnroe and Jimmy Connors. And with Luis Suarez being the man on everybody’s lips at the moment, I couldn’t help but think about what these iconic sports stars have in common. It is not only greatness… they are all famous for having lost control on the playing field. Is it anger? Frustration? Passion? Call it what you may, but each of these guys ‘crossed the line’ in the eyes of the public. For the life of me I have been trying to understand what it’s all about. Suarez’s situation is such a pity: I think we are going to lose one of the best footballers from the World Cup because of nothing but pure stupidity.What’s with this behaviour? How could Suarez go so far? Some sports psychologists say that it can happen in high-pressure situations concerning winning and losing. When people get angry the heart beats faster, blood pressure rises and then testosterone levels can rise, that’s when people lose control. Psychologist Dr Saima Latif, feels that Suarez’s behaviour of biting is a habitual and a child-like behaviour. He goes on to state that biting is an act of frustration, stress and loss of control. At the time of the incident Suarez is likely to have felt humiliated and put down in some way and wanted to get one over on his opponent. Most people know how to deal with such emotions in an adult environment. Somewhere along the line in his life as a young boy he was never taught how to deal with these types of frustrations in a normal, rational manner. It is stated that perhaps his biting started as a young child and was triggered by something; perhaps he was bitten himself. In any event, he needs help.I don’t mean to trivialise this in any way, but I almost agree with the sentiments of Ian Wright when he said he feels sorry for him. Regardless of his status, talent or salary, the fact of the matter is that the boy needs help. Suarez’s embarrassing attempts to deny culpability and shift the blame is further evidence of a childlike mentality. If you have children then you’ll know all too well that when they are confronted with the consequences of their actions they will try to deflect the blame or change the story. The crucial element of Suarez’s story is that this is not a one-off – he has a history.So, here we are at one of the World’s greatest sporting events and the talking point thus far is not the great goals that Van Persie, Messi or Suarez have scored; we are all talking about Luis Suarez’s sinking his teeth into his opponent. I will be surprised if Suarez is allowed to play on, which would really be a pity for the World Cup in general. Let’s hope that wherever this fantastic athlete plays next year – whether it’s Liverpool or somewhere in Spain – he is able to get psychological help so that we can talk about his greatness as a footballer!
