but that's the thing. there is a risk/reward analysis that the clubs directors will do. it is up to them to decide if it is worth keeping an unhappy player. conversely a player can then rightly gauge the situation and if he wants to leave, can put in transfer requests, pout, refuse to train, go the gallas route and say 'i'll put in own goals', etc to get out.
keeping unhappy players is detrimental. in some cases, after speaking to the gaffer, the player stays (or the gaffer feels that a pouting player can be 'handled")
this whole spurs thing is stupid, because martin jol even said last year that berbatov always was thinking about united. this isn't something new. levy and ramos know that berbatov doesn't want to be at spurs. this is just to cover his arse from the spurs fans.
i still maintain that there should no 'tapping up' rules. players who get their head turned are interested in other opportunities regardless if there is interest in them or not.
it is why there are never stories of scholes being 'tapped up'. or g. neville. because clubs know it would be useless to 'tap' them up.
it is the responsibility of the respective clubs to keep their players happy and to gauge their situations and deal with any misgivings.
