Kaka has denied reports he has agreed a move to Paris St Germain and insisted he is committed to Real Madrid.
Reports in Italy claimed the Brazil international had agreed a deal with the French club, now coached by Carlo Ancelotti, under whom Kaka played at AC Milan.
But the 29-year-old said on Twitter: "It isn't true that I have made any agreement with another club...
"I am totally focused on following my personal and collective goals at Real Madrid."
Kaka has struggled to repeat the form he showed at the San Siro since his move to the Bernabeu with injury hampering his progress.
The midfielder, a former winner of the Ballon d'Or and FIFA World Player of the Year awards, signed a six-year deal when he joined Madrid in June 2009.
