Florentino Perez won't spend his entire transfer budget on bringing Kaka to Real Madrid.
The Real presidential hopeful told AS: "We will not pay more than £50 million for Kaka from Milan."
Meanwhile, Brazilian media sources say an agreement has already been struck over personal terms between Perez and Kaka's minders.
The deal will be for five years and worth £8 million-a-season to Kaka, with a 50:50 split of revenue from image rights.
The agreement will make Kaka far and above the highest paid player at Real, with skipper Raul the next best on £6 million-a-year.
