Real Madrid coach Jose Mourinho says that he does not know if Kaka will still be at the Bernabeu at the start of the season.
Kaka's agent revealed this week that he was in talks with AC Milan over the Brazilian's possible return to the San Siro.
The transfer fee and player's wage demands represent significant stumbling blocks, and Mourinho has explained that it is too early to tell if the proposed deal will go through.
