Stoke City chairman Peter Coates is confident that £5million summer signing Tuncay will eventually prove his worth at the Britannia Stadium.
The 27-year-old Turkey international was unhappy at being substituted just seven minutes after coming on as a replacement in the 2-1 loss at Hull City - being sacrificed following the dismissal of centre-half Abdoulaye Faye.
Coates told The Sentinel: "He wants to play, like every other player wants to play, but these things happen.
"I am sure he will be fine. We are very pleased to have him at the club and I am sure Tony (Pulis) will find the right role for him and he will be a good player for us.
"It is competitive and everyone has to earn their place. He is no different to anyone else in that respect.
"It was unfortunate for him to go on and then come off so soon after and he is bound to be disappointed.
"But you have to go forward and it is up to us to manage the situation well.
"Sometimes things take longer than people want and I know our supporters are anxious. But we just want to win football matches.
"Tony tries to pick the best team to win him any particular game and he will make substitutions for the same reason."
