The Brazil star has so far endured a stop-start career since moving to the Bernabeu from AC Milan for a reported £56million fee in the summer of 2009.
This season the former World Player of the Year has actually enjoyed his best spell - and relatively injury-free one at that - under Jose Mourinho but this has not stopped rumours of a move away from the Spanish capital from growing.
"He doesn't believe in winter departures," Kaka spokesman Diogo Katscho told L'Equipe.
"The sums involved are very big and a transfer is something that has to be sorted out calmly, not in a rush.
"Kaka is also satisfied at Real.
"He feels much better, is back in the Brazil team and doesn't want to leave.
"A winter departure is almost impossible."
Adding fuel to the speculation has been the appointment of Carlo Ancelotti as the new manager of Paris Saint-Germain.
French media had reported that PSG was looking at spending €61.5 million to bring both Kaka and Pato - both players played for the Italian at AC Milan - to the Ligue 1 side.
However, Ancelotti has since come out and denied the claims which now appear to have been backed by these latest comments from Kaka's representatives who insist the player is going nowhere.
