The Brazilian's representative has ruled out a switch to Brazil or the MLS, but has revealed there is interest from England and Serie A
The Real Madrid midfielder revealed his desire to quit Santiago Bernabeu on Thursday, after a disappointing four years in the Spanish capital.
The Brazilian was a bit-part player under Manuel Pellegrini and Jose Mourinho but had hoped to kickstart his career in Madrid under the man who transformed him into one of the best players in the world at AC Milan, Carlo Ancelotti.
However, Kaka is yet to make a first team appearance under the Italian this season and his agent Diogo Kotscho believes a return to Italy or a Premier League switch is a very realistic possibility.
He said to Radio ESPN: "It's hard to talk about a possible destination now, but there is interest, including teams from Italy and England. It's hard to say where he is going now. It's not a secret that Kaka wants to go back to Italy but that depends on a lot of things.
"The Brazilian transfer window is closed. So is the one for the MLS. He wants to live in the United States in the final years of his career and sees some possibilities, but it will not happen at this moment."
The 31-year-old scored twice on Thursday night as Madrid beat Deportivo La Coruna 4-0 in a friendly to lift the Teresa Herrera trophy.
Kaka's current deal expires in June 2015.
