I think this deal has some financial reasons. With the transfer of Arda, barca will sell;
1- A lot of Arda kits in Turkey (Turkish people will not buy Atletico kit for Arda but they already buy barcelona kit, with Arda's transfer it will go wild.
2- La liga boardcast rights in Turkey will be much much more valuable.
3- Something about Turkish airlines being the sponsor of barca....
Arda is the captain of Turkish national team and has a lot of Turkish fans (not only Galatasaray fans). So barca will raise their market in Turkey.
