Kaka is still a class act despite the injuries and other difficulties he's had at RM.
If he gets his next move right, i.e. it's purely a footballing decision, people will soon realise how graceful and effective a footballer he can still be. Best number 10 since Zidane.
If he was still the business Milan would be back in for him. Undoubtably a great player (once?) but not what we are about now. We are about talent, competition, hard work, and 100% commitment.
