I think that if Man City make an offer of around 50 mil € for Buffon we'd be crazy not to accept it.
As much as I love the guy, and I really do, we need the money. Let's look at our rivals.
Inter never really have money problems, they have Moratti who, although not as rich as Abramovich or the Oil head at Man City, pumps in enough money to get the players he wants.
Milan, if they sell Kaka, will have an incredible amount to spend, and could get a lot of quality players, even if their prices inflate. Imagine if they get, as rumored, Clichy, Essien, Adebayor, get a new defence, a new playmaker etc, while we'd be left with a 30 year old Buffon, 32 year old Del Piero, 36 year old Nedved, with Molinaro, Grygera, Marchionni etc.
I dont thing we'd be able to compete with them for a few years.
