The 27-year-old has been linked with a move to the Spanish giants Real Madrid.
“I’ll say for the last time and I mean the last time. I do not want to leave Milan,” Kaka told La Gazzetta dello Sport.
“I beg you, in this moment I would prefer to be silent because I don’t want to be badly interpreted or, worse still, manipulated.”
AC Milan vice-president Adriano Galliani said earlier on Monday: “On the rumours that regard Kaka I repeat that he is still a Milan player. There is no doubt he is the object of desire of two important European clubs, just like Pato.
“This means that they view Milan well and we will look to resist the assault from European clubs that make more than us and have different tax rates,” Galliani concluded.
Kaka almost left the Rossoneri in a £107million move to Manchester City in the January transfer window.
