Well if no one on your team has balls, nor hunger to win, I would behave like that, too. Anyone with a mentality of wanting to win, would also lose their temper if they were on a team that lacks ambition. It is one thing to lose doing your best, and another very different is to lose having the tools to win and knowing that you can do it better, but at the end you don't. This is the thing that is happening a lot in Arsenal, where Wenger is making too many mistakes, that not only is costing him points and prestige of the club, but also is he is pissing most of his players, like Alexis among others. Even Henry thinks that Alexis should leave the club, since is not doing well for his career
