Kaka has recently been strongly linked with a move to French giants Paris St Germain.
"At no time did [those rumours] come from me, nor were they my will," Kaka told AS.
"I discussed it with Florentino and Mourinho. We talked and I was assured it was not going to happen.
"Speculation always exists - it is not the first time that they say I am leaving! But, I have always said my desire is to stay and succeed here.
"I keep working and eventually people will see the truth."
