Manchester City have joined the race to sign Serbian winger Milos Krasic.
The 26-year-old has emerged on the radar of a handful of clubs across Europe, with both Manchester United anc Chelsea keen to sign the Juventus star.
Roberto Mancini is the latest name to join the race, with talkSPORT claiming the Citizens chief is reportedly considering a player-exchange deal involving left-back Alexander Kolarov.
The bianconeri have signaled their intent to keep hold of the player though, with Giuseppe Marotta saying the player will not leave the club in January.
"We will not let him leave Juventus in January but there has been interest from other clubs," said Marotta.
"This is totally ruled out. He is our player and is not going to be transfer listed or sold.
"He is our future and there is no reason to think otherwise."
Manchester United manager Sir Alex Ferguson is a long-term admirer of Krasic, with the Red Devils chief thought to have first taken notice of the player two years ago.
Linked with a move to Old Trafford this summer, Manchester United are unlikely to let the player join one of their rivals without a fight.
Manchester United skipper Nemanja Vidic could also play a role in trying to persuade his compatriot join the club.
Branislav Ivanovic may look to play a similar role at Chelsea, with the Stamford Bridge side potentially looking to use the defender in an effort to manipulate a Stamford Bridge switch.
The Blues were also linked with a move this summer, whilst former manager Carlo Ancelotti was thought to be an admirer of the player during his time at Chelsea.
Whilst it's unclear if Andre Villas-Boas is a fan of the player, Chelsea owner Roman Abramovich is reported to be an admirer.
