Toure has been humiliated by his omission from Manchester City's Champions League squad, says Dimitri Seluk.
He told the Sunday Mirror: “It is Pep's decision and we must respect that.
“If he wins the Champions League for City this season then I will travel to England and I will say on television that Pep Guardiola is the best manager in the world.
“But if City don't win the Champions League then I hope that Pep has got the balls to say that he was wrong to humiliate a great player like Yaya.
“This is Pep's decision and we must respect it.
“Yaya is a professional and so he will do everything he is asked to do.
“Perhaps Pep will think he is good enough to play in the final 10 minutes of a League Cup game against a third division team – and, yes, I am joking.
“But what I can tell you is that Yaya will spend the season at City. He will not be leaving in January. He hopes that he will get the chance to prove himself."
