Chelsea have been put on red alert by the news Claudio Marchisio could leave Juventus this summer, talkSPORT has claimed.
The 32-year-old struggled for fitness this season and failed to make an impact with the Bianconeri as they went on to win their seventh consecutive title.
Recent reports have claimed that he may decide to leave the club although his father says the player's desire is to stay at Juventus.
"Claudio is calm and for a few months has been in good shape, working hard and ensuring he is always ready, but then the Coach makes his decisions," Stefano Marchisio told juvenews.eu.
"If it were up to me, I'd make it like basketball with unlimited changes to increase the intensity of games, but I know that's a utopian vision. Everyone wants to play, but that is football.
"I always hope that Juventus will win and Claudio plays, but it depends on a thousand different factors.
"Claudio still has another two years on his contract, as he wants to respect, because he cares for the club. Many untrue things have been said.
"People already thought we were in Germany, England or the United States.
"If the club says that Claudio is no longer part of the project, then we'll start worrying about it."
