Real Madrid are considering selling Kaka in January to fund Cristiano Ronaldo's new contract.

The spending power of PSG has Real president Florentino Perez concerned, particularly with Ronaldo's agent Jorge Mendes now getting closer to the club's Qatari owners.

Marca says Florentino is ready to improve Ronaldo's contract and fund the deal by cashing in on Kaka.

Kaka's father, Bosco Leite, has already informed Real his son is now ready to pursue his career elsewhere after previously digging in his heels when given the option to leave.
