Arda Turan will play on loan with Turkish club Istanbul Basaksehir in a deal covering 2 ½ seasons.
Barcelona have confirmed that Arda Turan is set to leave the club and join Istanbul Basaksehir on a two-and-a-half year loan deal.
"The Turkish International leaves the Club after two and a half seasons in which he has won everything there is to win domestically with the blaugranes".
Barcelona still have the option to sell Turan in any transfer window during the loan period, which is to conclude around the time that the midfielder's five-year contract ends.More news: Blaze Bernstein case: Suspect identified in University of Pennsylvania student's death

The Istanbul football club quoted chairman Goksel Gumusdag as saying: "Today, Arda Turan is coming back to his country with an orange kit [of Basaksehir] on him".
Turan made just 55 appearances for Barça in two-and-a-half years, scoring 15 goals.
The midfielder claimed six titles with Barcelona: one La Liga, two Copa del Rey, one Spanish Super Cup, one Club World Cup and one European Super Cup.
Barcelona announced the signing of Turan from Atletico Madrid for an initial fee of £24m in July 2015 but, due to their 14-month ban on registering new players, he could not make his debut until the start of 2016.
