Edin Dzeko is facing a row with Manchester City boss Roberto Mancini.
Dzeko played for Bosnia-Herzegovina against Wales with a knee injury.
Bosnia coach Safet Susic revealed the striker had made the decision the feature in the midweek international despite his knee problem.
He said: "There was a question about him starting because he has a problem with his knee and maybe he should not have played. But I left it for him to decide whether he wanted to.
"There was a problem with his knee. We spoke and I said it was up to him.
"Dzeko is the top player in our team. And he can play in our team as long as he wants unless he asks to be substituted."
