The report adds the shock deal would be worth £35 million, a relatively low return for one of the world's best defenders and a player who signed a new contract just last season.
It recently signed Andre Silva from Porto, Ricardo Rodriguez (Wolfsburg), Franck Kessie and Andrea Conti (Atalanta), Mateo Musacchio (Villarreal), Fabio Borini (Sunderland) and Hakan Calhanoglu (Bayer Leverkusen).
It is being reported that he will undergo his medicals later in the day before signing a five-year deal with a salary of eight million euros ($9.16 million) per season at the club that now boasts a project to take it back to its glory days.
According to Fabrizio Romano, a well respected journalist in Italy, claims that a deal to take the 30-year-old to the San Siro is a done deal.
Juventus have made an initial tentative approach for Borussia Dortmund defender Sokratis Papastathopoulos, who has also been linked with a move to Chelsea and Manchester United this summer.
After the final of Champions League, where Juventus lost to Real Madrid, a reported bust up between Barzagli and Bonucci laid the foundations of the current scenario. "There are times when you should turn a blind eye and times when you have to have your eyes wide open and in that moment Leo was wrong", he was quoted as saying by the Daily Mail.
Speaking to RadioVS earlier, Goal Italia journalist Romeo Agresti confirmed that the player is leaving Juventus, in part due to a falling out with Max Allegri.
