Yaya Toure: His agent must apologize or Pep won't let him play

Yaya Toure's agent said a few weeks ago Pep Guardiola should apologize for leaving him out of the Champions League squad. He said: "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".
Now Guardiola is the angry one who wants to hear an apology. He said: "He must apologise. If he doesn't, he won't play".
Just in the case that "he has the courage to call me, go to the media and say apologise to Manchester City, the first one, the second one is his team-mates and after the trainer. When that happens Yaya will be part of the group and he will have the same chance to play all the games.
"Because I cannot accept as a coach, every manager when his player doesn’t play goes to the media and speak and speak and speak. It depends. I know how Dmitri Seluk loves to Yaya Toure, if he loves me, show me and make apologise to Manchester City what he did in the [media]. I cannot imagine in my period when I was a football player, my manager going to the media and speaking about this and about that".
The 33-year-old made this season just one appearance for this season. Will it be his only appearance or will his agent apologize?
Is Pep's behavior childish?
