Paris Saint-Germain sporting director Leonardo has hailed the quality of Kaka, describing the Real Madrid talent as 'an extraordinary player'.
The 30-year-old playmaker has been linked with football away from Madrid in recent times after struggling for fitness and form since arriving at the Santiago Bernabeu in 2009.
PSG has been suggested as a likely destination for Kaka, and Leonardo, who is a close friend of the midfielder, still rates the former AC Milan star highly.
"Kaka is surely a great player, with enormous potential," Leonardo told O Estado de Sao Paulo. "But he has suffered severe injuries, which damaged him.
"He is at a very competitive club, in which everything happens very fast. But he has not lost the hunger for the game.
"I am very close to Kaka since the start of his career. He is an extraordinary player, even when he is not at 100 percent.
"But we have not begun signing new players yet."
Leonardo then admitted that he is not surprised to see PSG linked with a host of big-name players, with reports linking the club to moves for Madrid striker Gonzalo Higuain and Milan starlet Alexandre Pato.
"PSG are on the buyers' group now," he explained. "As such, for any important player, we are potential buyers.
"Fifty thousand names will be linked to us. We will make investments, yes. But we are still studying."
