You are wrong here Andy. Wages, especially in Italy, present around 70% of the whole deal. As Wenger said, it's all about the wages today and sooner rather than later there will come a time when transfer fees will not exist anymore and players will be signed only for wages.
Juve are allready paying +100m eur a year only for the wages of our players. We have a budget and the greatest part of it goes for the salaries. If we sign new players, don't sell the players we have and pay the new guys 10m eur for their salaries it means that together with the taxes we'll be paying 20m eur more than the previous year. So we pay 20m eur more from our budget which means that we'll have 20m eur less for transfers next year.
Milan were in big shit due to this. They had old players under contract, they couldn't get rid of them and it was hurting them on the mercato in the last 2 summers. This summer they got rid of Cafu, Serginho and Ronaldo and only this way they saved ~20m eur they've been paying for their wages. These money were enough to pay for Ronaldinho's and Zambrotta's wages.
It works much differently than some of you guys think.
Teams like Roma and Fiorentina will go bankrupt in no time if they start giving the wages Juve are giving to their players. That's why they are forced to sell a player each summer and they can't buy the better players who ask for 3-4m eur per year. Juve don't have to sell their stars and we can offer the better players the wages they want, but still we can't buy world stars and offer them crazy wages, something Milan and Inter can easily allow themselves.
Face it people. Yes, we're Juve bla bla bla, resistance is futile bla bla, but you conviniently forget something.
2006/07 - Inter and Milan got ~100m eur for serie A tv rights, we got shit. Inter and Milan got at least as much from playing CL, the tv rights from there etc. Sponsors were fighting to have their names on Milan's or Inter's jersey while we lost our main sponsors.
That's more than 200m eur difference only for the last 2 years. Milan and Inter didn't have to sell all their players, they already had a big squad, so now they have players like Oliveira, Gilardino, Suazo .... players they can sell for 10-15m eur without suffering a bit. We don't have such players to sell, earn millions and play a big role on the mercato.
