AC Milan coach Massimiliano Allegri has played down reports linking Kaka with a return to the San Siro after his agent was spotted in Italy.
Kaka left Milan to join Real Madrid in a €68.5 million deal in June 2009 but the Brazilian struggled to make an impact at the Bernabeu during an injury-plagued first season.
Bosco Leite, Kaka's agent and father, was spotted in a meeting with Milan sporting director Ariedo Braida at the club's Via Turati headquarters last week, leading to reports the playmaker was set to return.
However, Milan coach Allegri claims he is not thinking of re-signing the 28-year-old at this moment in time, although he did admit Kaka was a player he admired.
Allegri told the Gazzetta dello Sport: "Kaka is an extraordinary player, but at this moment we don't have time to think about such things. Can calls for his return create problems in the dressing room? No, these calls are not able to disrupt the harmony of the team."
"At this moment, we are in a fundamental stage of the season, and it is necessary for me to concentrate on the Champions League match with Real Madrid, and the Serie A matches with Juventus and Napoli. I have no opinion on a transfer for Kaka, because there are three months until the transfer window, and we are competitive with the players that we already have."
Although poor form and injuries have blighted Kaka's time in Madrid, former Milan team-mate Clarence Seedorf doesn't believe he will quit Real after just one full season at the club.
"It's something unreal. Kaka is a friend and a great player, but I don't think there is any truth in this," Seedorf said. "He is recovering from a big injury, and I hope he returns to form soon."
