Juventus have reportedly turned down an official approach from Manchester City for midfielder Miralem Pjanic.
The Premier League champions are understood to have identified Pjanic as a possible alternative, but Tuttosport claims that Juventus have rejected their €50m (£43.7m) offer.
The report suggests that Juventus value the Bosnian playmaker higher than that, and are reluctant to sell due to their concern that they may not be able to replace Pjanic this summer.
Guardiola, meanwhile, is on the lookout for a long-term replacement for Fernandinho, who is now 33 years old.
Jorginho is still thought to be City's first-choice target, but Napoli's refusal to sell has led to them drafting a list of other options.
