AC Milan recently brought in their former star Kaka on a free transfer from Real Madrid after having sold him only four years ago for € 63 million.

Kaka was allowed to leave AC Milan back in 2009 due to the severe financial problems faced by the club. Since the departure from the San Siro, Kaka has not been the same player.

He has struggled to live up to the expectations at Real Madrid, while he has been consistently overshadowed by another star Cristiano Ronaldo at the Santiago Bernabeu. Several injury problems during the last four years have also not helped him either, though if you'd have bet at william hill on him making a San Siro return you wouldn't have got very good odds!

He revealed in the last few days that he was about to exit Real Madrid in search of regular first-team football because he wanted to play for Brazil at the World Cup. He rejected the possibility of returning to Brazil.

The 31-year-old has now taken a huge pay cut in order to join AC Milan, who recently sold Kevin Prince Boetang to Schalke. One of their main rivals for the title – Inter Milan, though, appear to be happy with the signing. According to Inter president Massimo Moratti, Milan have done extremely well to bring back Kaka to the San Siro.

"The decision to bring back Kaka is an excellent move by Milan. As for sticking to tradition, it's for them to decide [whether Kaka is still of added value], so I'll pass no judgement on that. But I'm glad we'll see Kaka playing in Italy again," said Moratti on the official website of Inter Milan.

Kaká played for Milan between 2003 and 2009. During this period, he made193 league appearances for Milan and scored 70 goals. He also won the FIFA Ballon d’Or award during his time at Milan. The Champions league and the Serie A title was the major honours he won.
