The issue remains of convincing Arthur to swap Catalonia for Turin, something that has progressed but isn’t certain.
Sky Sports adds that talks are still ongoing between Juventus and Barcelona about Pjanic’s value.
Juventus rate the 30-year-old at €70m, but Barcelona do not believe there is a €10m difference between Pjanic and Arthur.
The Old Lady have offered a €5m-a-season salary to Arthur, which is a major upgrade on his Barca deal.
But the former Gremio star has yet to give his final approval for the deal to go ahead.
Arthur joined Barcelona two years ago in a deal worth up to €40m, meaning his value has essentially doubled.
