Thats unrealistic atm. Napoli would accept a 35mil bid, Cavani would be more than pleased with a 4-5mil salary, before taxes, thats what he asked from Napoli. (and unlike RVP who wants more from Arsenal and thats why he is leaving)
We usually spend at max 25mil for our star signing(Amauri, Diego, Melo) and we have a budget of at least 50mil without considering the income from sales.
30mil spent on the 2 CMs, means that we at least have 20mil more, Krasic and Elia sales will fund the Giovinco return, even if we overpay, to get him back and sell off the other two, as we usually do because of Marottas poor negotiating skills.
If the Turks wont give us, not even half of the invested money on Melo (12mil) we should get him back, sell him to the EPL, or use him to this deal as a 10mil bargain chip.
Both players cost more than 15mil, but due to Marottas poor negotiating skills lets say that he will use one of them to the Cavani deal, as a 10mil bargain chip only, so we would only need to add the usual 25mil, on three year installments...
easily do-able! The most reallistic chance we have.
