AC Milan manager Massimiliano Allegri is unsure of the likelihood of pulling off a sensational swoop for Kaka.
The Brazil international spent six years with the 18-time Serie A winners before joining Real Madrid in 2009, where he has enjoyed mixed success.
It is difficult to speculate on the percentage for Kaka, but as a coach I look at this issue with great interest, Allegri told Rai Sport.
The 45-year-old also spoke about bringing lifelong Milan fan Mario Balotelli to the club, as well as the possibility of making other signings.
Balotelli is a Manchester City player, and I have not spoken with Roberto Mancini about him, and I think he still has continuing and important qualities, said the former Cagliari coach.
I do not think there is the need for reinforcements in defence: Mexes [own-goal in Sunday s Serie A win over Bologna] was a simple accident, which occurred after a positive performance, and we have many good players in that department.
I think a coach, like a business leader who has people under him, needs to know how to wait patiently for the results of the work.
