Barça had hoped that everything was sorted with Arda, but his return to Turkey has not been quite what was expected and the Turk could yet be a problem for Barcelona.
Other than his ban for his fight with a colleague, the midfielder failed to return in good form and has had a very disappointing campaign for the Turkish side.
While at Barcelona they hoped that he would regain his form in Turkey, the reality has been shown far from this.
In the recently completed campaign, Turan did not even play in the Europa League and played only 14 matches in the Turkish League, in what has been an extremely below par season for the Turkish international.
He still has a year left on his contract at Barça, so they will have difficulty getting a lot for him, which, will make this deal one of the worst in Barça's history.
