actually, the so-called 'buste' are simply 'envelopes' in which every team puts his offer (hidden from the offer of the other team of course) and then, the higher offer gets the player. So it's a blind auction, yes!

whatever it is, i think we'll have all the possibilities to get back whoever goes the other way. This is in some aspects better than loaning, because with a loan, players are very often not treated the same (e.g. giovinco; why was he benched so often when he clearly was the best man for his team...)
