Chelsea boss Antonio Conte is monitoring Leonardo Bonucci's situation at Juventus.
Calciomercato.com says the Italy international had a heated row with Juve boss Max Allegri during their 4-1 victory over Palermo last week.
Since their spat, Allegri has left Bonucci out of Juventus' Champions League squad to face Porto tonight.
And his treatment of the 29-year-old could lead to him questioning his future - with Chelsea and Manchester City keen.
Bonucci reportedly feels betrayed by the decision, claiming the club didn't support him.
