The 29-year-old, who was influential in Madrid"s 5-0 win over Espanyol last Sunday, is continually being linked with a move away from the Santiago Bernabeu.
However, speaking to Spanish newspaper AS, the midfielder insisted that he is determined to succeed with Los Blancos.
Kaká said: “I want to stay here, absolutely. I am not going anywhere because I want to succeed at Madrid.
“It is simply not true that [head coach Jose] Mourinho has no faith in me."
Kaká"s contract with Real Madrid runs until June 2015.
