Then maybe I should mention some of the drama that surrounds him. It was reported that Arthur at first did not want to come to Juventus. It was then reported that Barcelona were forcing him to accept the deal that would see Pjanic head to Juventus and Arthur to Juventus. Eventually, Arthur accepted and the parties finalized the deal.
