Of course he should follow examples of well behaved players, but it isn't as black and white as you make out. He could be one of the worlds best like Giggs and Rooney, have the most successful career at Man Utd as possible and still be a little shit off the field. George Best anyone? Obviously I want him to be well behaved and not follow suit off the field as pre-mentioned naughty boys, but I was just pulling you up on your comment of "if he wants to succeed" It just comes across like if he doesn't be a good boy he will be a failure which isn't true.
Point taken. But the problem with that logic is that for every George Best that we can find, there will be a Ravel Morrison, Balotelli, Adrian Mutu, Kezman, Adriano, Bentley, Etherington, etc2 who had so much potential but did not quite fulfil it due to off the pitch issues. Of course there will always be people who are like you say, shit off the pitch but absolute genius on it. But the likelihood of being successful on the pitch is much less if you have problems off it. Just my humble opinion.
