Over analyse, paralyse, you mustn't over analyse... Do you wake up at four in the morning and wonder who should be playing left-back? Four? I would love to sleep that long. If you want a really long career you have to find a way of switching off. I do it when I'm out walking my dog, Alex Ferguson got into horses, others get into wine. Some players like going shopping, which is not my scene. A lot of them turn to golf. I tried it, didn't like it. I have to walk. If I couldn't I'd be in a padded cell by now.
