The interest from theses two Clubs is not new & sounded even before the start of this current season. Both Clubs are deficit in the midfield area & are combing the market for a creative & play making midfielder. Kaka is currently getting playing time at Real Madrid, but timidly, & depends on how he evolves & improves if he is to win a permanent place in then Spanish Football Club.
Its a long time ( Football wise) until January & I suspect that for now Kaka is happy to stay at Real Madrid & attempt to win back the lost form. But said this anything can happen in 3 months; stay tuned!
