The hardest thing about the negotiations will be the economical differences, Real Madrid can offer Kaká a salary that Milan can't match. The Italians have had to sell Thiago Silva and Ibrahimovic due to economical difficulties, and so the return of Kaká would give fans a glimmer of hope.
The Real Madrid star knows his situation in the Spanish club is not the best, however it is reported the Brazilian is only prepared to cut his wages by 8 Million Euros. AC Milan have had to sell two key players, and they don't want to spend too much on Kaká, however much they want him to return.
It is expected Real Madrid president Florentino Perez will hold talks with Adriano Galliani regarding Kaká's future in 5 days, on the 8th of August, both will be hoping for a solution to benefit both clubs.
