Brazilian Kaka, the World Footballer of the Year, signed on Thursday a new deal with the European champions AC Milan to remain at the club until 2013, the Italian giant said.

The 25-year-old, whose current deal runs until 2011 and is believed to be worth 6 million euros a year, said this week that he wanted to spend the rest of his career with Milan.

Kaka signed for Milan in 2003 from Brazilian side Sao Paulo.
