He don't care because he is a h*** of a lot better manager than all of us put together. The problem is that fans post what they think about him on the net, not nice things, and then media use it and the player then read about it. He will say that he won't care but in the end it sticks when it happens day after day. That means that the player will be afraid that he will make mistakes because he know what will happen if he do. That means that the player won't play his natural game. Support the player and he will play better. He will get more confident and that helps the team.
