Excellent article from the Observer about AVB, so I won't post in full here.
But it does focus on AVB's fostering of a strong esprit de corps and that, central to that, is treating everyone as equal, regardless of reputation. Absolutely no favourites. It a policy that has proved popular with all the players.
This is, in large part, why AVB didn't summarily drop Brad and install Hugo as number one as soon as he arrived from Lyon - even if he might always have known that Hugo is the better keeper and would eventually claim the number one spot for himself. Had he done so, the team spirit that he had been carefully nurturing throughout the summer could have evaporated in an instant.
So there were bigger, far more important things at play than the mere choice between two keepers. AVB knew what he was doing.
Which has been argued by many all along. Putting the team ahead of individuals.
