Is it believed the Baggies and the Turkish top flight outfit made a breakthrough in negotiations and the midfielder is set to call time on two seasons as a permanent Albion player.
Yokuslu, 30, is thought to have favoured the move to his homeland and it is understood he has struck a three-year deal with the club he represented earlier in his career.
Yokuslu made a brief return to Albion’s training base towards the end of last week but he is now headed back to his homeland after departing the Black Country.
