Royalclapper Kaka returning to AC Milan was an interesting one. He seemed to be unstoppable at one point when he won the World Player of the Year in 2007 while playing for Milan and yet seemed to very quickly fade away thereafter.
Didn't live up to his billing at Real Madrid and you would wonder whether Gareth Bale can live up to the hype or if he gets weighed down by similar expectations. Kaka's best years are probably behind him but AC Milan might be hoping to get back what's left of his old self being as he's worshipped there.
He didn't want to leave AC last time though, did he? - didn't he feel like he was being forced out of the club (i remember Man City were very close to getting him before Real came in)
