Kaka has made a spectacular return to the club he rose to prominence with on a two-year deal.
The Brazilian midfielder spent six years at the Italian outfit following a move from Sao Paulo, a spell that saw him collect a Serie A (2003-04), a Champions League trophy (2006-07) and a Club World Cup (2007).
His stunning 2006-07 season saw him collect the 2007 Ballon d'Or award.
However, his €68.5 million move to Real Madrid in 2009 failed to live up to the hype and excitement, with his four long years riddled with injuries and bad form.
He has now been deemed surplus to requirement under Carlo Ancelotti, and his position at the club has been made redundant by the signings of Ozil and Isco.
According to Gazzetta dello Sport, Adriano Galliani's Milan has agreed on an unofficial deal with the Spanish outfit, in an attempt to bring their former midfielder back to the club that shaped him into one of the world's best.
Kaka himself will, no doubt, look to secure a first-team place in a bid to place his name on Brazil's World Cup roster.
His stint at Real Madrid saw him collect 29 goals and 32 assists in all competitions. And, Galliani has now confirmed that the deal has been agreed.
"Last night after 2000 CET, thanks to the traditionally good relationship between the two clubs, Real Madrid and Milan reached and formalised an agreement for the transfer of Ricardo Kaka into Rossonero colours," read a statement.
"And overnight, a little before 0300 CET in the morning, an agreement was reached with the world-class Brazilian."
