I think the days of managers being given total control of transfers are over with te money involved these days wrong decisions can finish a club.
Except for Fergie, lol
Not only Fergie but I would say many or at least all high profile managers. They are probably told the budget they have for tranfers and wages, but, have total control on who they would buy and sell, else they cannot be responsible for results. The committe is there to help them in their decision, not to decide. One of the stumbling blocks of Jose M coming to Chelsea is exactly that apparently, he wants to be in total control of transfers while Abramovich wants a big say, like bringing Shevchenko.
