Silly boy who has never grown up. Even if he is not a bad footballer he should be held as a prime example of what not to do to younger players. I really cannot see him changing now. You do need to be aggressive but it must be controlled. A good example has been Rooney even though at times he acts like a prima donna,at least he would draw a line at thuggish behaviour.
By the way I am a City fan who remembers the time when you could tackle and the game was played by men such as Tommy Smith, Norman Hunter and the best of all Mike Doyle.
