The defending English champions are growing in confidence that they will be able to sign Miralem Pjanic from AS Roma this summer.
Italian giants fear the £30million-rated Bosnia international has already decided he wants to leave and will not sign an extension to his current contract, which expires in 2018.
The free-kick master is currently earning £50,000 a week, but Chelsea are prepared to offer him a three-year contract of more than £65,000 a week to bring him to Stamford Bridge.
The attacking midfielder boasts the most assists in Serie A with 10 and has also scored an impressive 12 times in all competitions. It is believed he is interested in moving to Chelsea, who will have current Italy coach Antonio Conte in charge next season.
The 26-year-old has been a key player for Roma since joining from French club Lyon for £8m in 2011 and is also attracting interest from Real Madrid. Should Chelsea succeed in signing him, it will raise doubts over the future of Oscar, who is wanted by Juventus.
The Serie A outfits are also trying to fight off Chelsea’s interest in midfielder Radja Nainggolan and defender Kostas Manolas. As Standard Sport revealed last week, Nainggolan has been speaking to friends about the possibility of moving to Chelsea. However, Roma have tried to scare off Chelsea by valuing him at £40m, even though he turns 28 next month.
