When was the last time spurs got a trophy?! they are hardly a big club.You have to look at it from the clubs point of view as well. Would a big club want to take a punt on him and possibly endure trophyless seasons' all the whole hoping he is 'learning'? Especially when they can just hire an experienced and more proven manager such as Capello or at least someone more solid and dependable like United did with Moyes?
Managers and players can't be compared. If he wants to 'learn' at a big club, do it as a assistant, not as the main man which is absurd
