The Italy international is out of contract next summer and his former coach at AC Milan is keeping an eye on his next move
The Italy international is out of contract at Juventus as of next summer and Ancelotti - who coached the 34-year-old during his time in charge of AC Milan - is keen on a reunion with his former player.
Madrid could face the prospect of filling a big hole in their midfield should Xabi Alonso opt to run down his contract and move on in June and Giorgio says the Blancos coach remains a big admirer of Pirlo.
"Pirlo is a player who could fit into any side," the 66-year-old former Milan assistant told AS. "The only reason he left Milan was because of physical issues and not technical or tactical reasons.
"Ancelotti asked about him while I was at Chelsea, last season at PSG and even recently with Real Madrid, Pirlo is a universal footballer, the problem is Juventus are not that keen on selling the player."
Ancelotti has been linked with a return to the Rossoneri in the future, having lifted Serie A once and the Champions League twice in his eight years at San Siro and Ciaschini admitted the 54-year-old retains a strong affection for his old club.
"When Ancelotti talks about Milan he does so from the heart. I think he would be very happy in Milan again one day."
