The veteran full-back, who played for Los Blancos and Roma earlier in his career, believes the midfielder would have no trouble slotting in if he made the move to the Bernabeu
"Pjanic would fit at Real Madrid. He plays more or less like [Luka] Modric," he told Goal.
"If Real Madrid sign him, he will play very well.
"Pjanic is a key player to Roma. If Real Madrid stop him, Roma will lose a lot."
The 35-year-old, who is still playing in Turkey, also had some thoughts on Barcelona, and specifically his two compatriots currently starring for the treble-winners.
"Aleix Vidal's arrival to Barcelona will make Dani Alves work a lot more. But if he keeps his head, he will play for sure," he said.
"Neymar will be one of the best players in the world in the next year. He still needs to work.
"It could be too soon [for the Ballon d'Or] as there are some great players like Cristiano Ronaldo or [Lionel] Messi who are one step above. Luis Suarez is doing very well this season too."
