The Bosnia international has previously been linked with a move to Borussia Dortmund this summer to replace the Bayern Munich-bound Mario Gotze.
Tottenham Hotspur have also been mooted as admirers of the playmaker, and recent reports claimed Barcelona were preparing an €11million (£9.4m) offer.
Pjanic would not turn down the chance to move to the Nou Camp, but also conceded that Barcelona's arch-rivals Real Madrid are his favourite club.
However, Pjanic has echoed the recent sentiments of his agent by confirming he is happy at Roma and is in no rush to leave the Serie A club.
"I have been a Real Madrid fan since I was a boy," Pjanic was quoted by Oslobodjenje. "Certainly, this is my favourite club.
"Barcelona? Who wouldn't like to play for them?
"I feel good at Roma, though, and at this point I don't know if I'll leave this summer."
