AC Milan vice-president Adriano Galliani has rubbished reports Kaka could be on his way to Real Madrid or any other club at the end of the season.
Kaka turned down a world transfer record switch to Manchester City this week and reports in Spain have linked him with a summer move to Madrid.
Galliani, though, insists the Brazilian is no longer for sale.
''Kaka forever,'' said Galliani to the Italian press. ''He will not move, he will remain here for the next four and a half years or for longer.''
Primera Liga giants Madrid have long been linked with a move for Kaka but their hopes of signing the 26-year-old have always been dashed by Milan's unwillingness to sell.
But rumours that former Real Madrid president Florentino Perez could return to the club as a replacement to Ramon Calderon have fuelled speculation of a renewed bid for the forward.
Calderon resigned this week as Madrid president.
''If (Florentino) Perez was to ask me about Kaka I would say no to him as well,'' said Galliani, who admitted his club just wanted to put the Kaka saga behind them.
''I don't want to talk anymore about Kaka's situation. All's well that ends well. After this situation, I reiterate that Kaka will not move.''
Kaka is under contract with the Rossoneri until June 2013.
