Barcelona want to use Arda Turan in a swap for Arsenal fullback Hector Bellerin.
Sport says Turan has already agreed personal terms with the Gunners.
Bellerin could be swapped for Turan after the midfielder 'agreed' to join Arsene Wenger's side.
New Barca coach Ernesto Valverde is giving the green light on a move for the 22-year-old.
And with the new boss keen to overhaul the Nou Camp defence, Bellerin could fill the void so clearly felt since the departure of Dani Alves for beaten Champions League finalists Juventus.
Barca are, meanwhile, willing to cash in on Turan – and it sets up the possibility of a swap deal between the two clubs.
