The Bosnian midfielder, linked with a host of clubs over the summer including Tottenham, has enjoyed a good start to the new season.
Reports in the Italian media claim Roma want to talk with Pjanic - who has two-years left on his current deal - about a new contract.
However, the former Lyon star has explained to L'Equipe that he is not ready to talk.
"I have two years remaining on my current contract and it is not the right time to talk about it," he is quoted as saying.
"If the club wants to talk, there will be a better period for that. I am focused one just one thing so far, giving my very best to the club."
Pjanic had issues with former coach Zdenek Zeman last term, but he is now flourishing under Rudi Garcia.
"Since pre-season training, everything has been very clear between the coach and me," he said.
"Anyway I had no desire for anything else than another season here.
"I want to pay back the coach and the club for the trust they showed me. I feel at ease at AS Roma."
