JOIN USBrazilian attacking midfielder Kaka agreed his return to AC Milan on Monday after four unhappy years at Real Madrid, which saw him go from one of the world's top players to an injury-prone reserve.
The 30-year-old's dramatic loss of form has also seen him shelved from Brazil's plans for the 2014 World Cup after he was left out of the Confederations Cup squad this year.
Kaka has been plagued by injuries over the last few years, including one to his left knee shortly after the 2010 World Cup.
He made only 82 league appearances during his time at Real after his 65 million euro ($85.71 million) move in 2009 and rarely played anything more than a supporting role.
Milan said that Kaka, full name Ricardo Izecson dos Santos Leite, had signed a two-year contract for his return to San Siro.
The announcement of his return came two days after midfielder Kevin-Prince Boateng was surprisingly sold to Bundesliga club Schalke 04.
Milan said that Kaka, who won a World Cup winner's medal with Brazil in 2002, would arrive later on Monday.
