Juventus are watching Bolton Wanderers defender Gary Cahill.
Cahill is inside the final 12 months of his current deal and will be sold by Bolton in January if they fail to get his signature on a new contract.
Arsenal and Chelsea are both chasing the England international, while Turin sources say they will face competition from Juve.
Juve GM Beppe Marotta failed to land his centre-half signing in the summer and admitted on Sunday night they will be active when the transfer market reopens.
