The appointment of Massimiliano Allegri at Juve has clouded the future for Pirlo, who quit AC Milan two years ago after falling out with his new boss.
Tuttosport says Ancelotti has already made his move and tested the water with Pirlo about moving to Madrid.
Despite penning new terms last month, the veteran is now unsure about playing under Allegri, who is due to meet with Pirlo today.
At yesterday's unveiling, Allegri insisted he wanted to work with the Italian legend and sources close to the Juve coach say he will relay much the same today to Pirlo.
