The Brazilian star has been the subject of a bid from Chelsea, which was confirmed by Milan vice-president Adriano Galliani yesterday.

"When I return to Italy I will know what's going to happen, but at the moment nothing is certain," said Kaka. "There are two teams who are very interested in signing me, but now I do not want to talk about it.

"Until we return to Milan and know how things are, we cannot decide what happens with my future."
