Brazilian midfielder Kaka returned to AC Milan on Monday (September 2), after leaving the club for Real Madrid in 2009.

Kaka agreed his return to AC Milan after four unhappy years at Real Madrid, which saw him go from one of the world's top players to an unhappy, injury-prone reserve.

The 31-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 move in 2009 and rarely played anything more than a supporting role.

He was called up for a pair of friendlies last year and performed promisingly but has not been selected since a 1-1 draw against Russia in March, when he clearly failed to impress new coach Luiz Felipe Scolari.
