The 22-year-old forward has attracted interest from a number of European clubs ahead of the January transfer window, as he continues to excel in Serie A.
Spurs boss Andre Villas-Boas is rumoured to be considering a bid to bring Pjanic to White Hart Lane, as he continues his search for a replacement for Luka Modric, who swapped north London for Spain, signing for Real Madrid in the summer.
The highly-rated Bosnian international first caught they eye during his time in France with Ligue 1 giants Lyon, earning a switch to Italy in August 2011.
His impressive performances at the Stadio Olimpico has also alerted Barcelona, with Tito Vilanova contemplating an attempt to lure Pjanic to Camp Nou.
However, both Barca and Tottenham's hopes of securing the player's signature have been dealt a blow after he' revealed his intention to honour his contract at Roma, which runs until the summer of 2015.
"I am happy at Roma because the fans love me and my work is appreciated by everyone," Pjanic said in L'Equipe. "Of course you never know what can happen, but I am under contract and I want to fulfil it."
