We all know what he can do, his ability is without question but its his lack of application and commitment which is the issue.
People use to say the same about Balotelli but three or four managers later he is still looking to be 'loved' helped with his demons etc. Some players just do not want to put the hard yards in to make the most of their ability.
He could be fantastic next year, I have a sneaking feeling he may be, but it depends on which Nasri turns up and so its a gamble and personally if we can get someone in who we know will be committed to the cause and of similar ability why take the risk??
