Kaka has set himself a short-term target of scoring his 100th goal for Milan as he prepares for his first game back with the club.
The 31-year-old Brazil international has returned to Milan after four seasons with Real Madrid and wants to quickly score five goals to reach the 100-goal mark for the Serie A club.
Kaka could play for Milan against Torino on Saturday and speaking ahead of the trip to Turin, the veteran attacking midfielder underlined how excited he is at the prospect of pulling on the red-and-black-striped shirt again.
I am happy with all this enthusiasm, Kaka said.
I am training well and feel like a kid about to make his debut.
Kaka scored 95 goals in 270 games for Milan between 2003 and 2009 but only managed 29 in 120 matches for Real.
The Brazilian wants to become a goalscoring threat again on his return to the San Siro.
I am targeting a place at the World Cup but above all to do well here, Kaka said.
I promise the utmost effort and one of my objectives is to reach 100 goals for Milan.
I only need five and hope to get there soon.
