At a time when the Italian giants are hoping to sign Paul Pogba from Manchester United, Pjanic is expected to leave after a four-year spell in Turin.
Although a number of reports have suggested that Barcelona are the favourites for his signature, it appears that the Spanish outfit have previously failed to bring in the Bosnia-Herzegovina international.
According to AS, Barcelona first wanted to sign Pjanic in 2016, a time when the player ultimately decided to leave Roma for Juventus.
The report adds that a deal could have materialised in 2017 and 2018, only for one of the relevant parties to be against a transfer at the time.
The two clubs are said to be holding discussions regarding a move at the end of the current campaign. body check tags ::
