100% about Brady, I cannot warm to him at all - as you say, to be that good at anything, you need that arrogant streak. He almost comes across as a psychopath, but I remember reading a book that basically said all 'greats' had psychopathic tendencies.
Him & Wagner are a right pair, it's a good watch but has none of the warmth of the Wrexham or Sunderland (IIRC was some time ago) docs
