The 24-year-old has been in fine form for the Giallorossi this season, notching five goals and six assists in 31 Serie A appearances.
His performances are reported to have aroused interest from Manchester United, Liverpool, Tottenham Hotspur and Paris Saint-Germain in recent months.
However, despite admitting interest in moving on, the playmaker maintains he is yet to make a decision regarding his future.
“I’m used to these rumours but at Roma I am fine,” Pjanic told Gazzetta dello Sport. “I still have a year of the contract and I do not know what will happen.
“There will come a time to think about the contract and transfers but it will be after the World Cup.”
Pjanic joined Roma from French side Lyon in the summer of 2011, and has been a key figure this season as the Stadio Olimpico club secured a return to the Champions League for the first time since 2010/11.
