Barcelona have allowed Arda to depart on a two-and-a-half-year loan agreement to Turkish side Istanbul Basaksehir
The 30-year-old playmaker returns to his native Turkey having failed to make a single appearance under Ernesto Valverde this season.
A statement on the club’s official website read: “Arda Turan has played a total of 55 games for Barca, scoring 15 goals in his two-and-a-half years as a Blaugrana.
“In that time he has won 6 trophies: 1 league championship, 2 Copa del Rey, 1 Spanish Super Cup, 1 Club World Cup and 1 European Super Cup.
“As such the Turk leaves after completing a clean sweep of domestic trophies.”
