Manchester City was already acquitted in this regard. If the current issue is independent of this, there is a possibility that they will be banned from European cups again. If they are banned from European cups for 2 years, Pep can leave the team. I think he has very strong opinions about it.
It doesn't even need to wait for UEFA to ban city to make pep leaves from city. If premier league will be giving a serious sanction and that will be enough for pep to leave from manchester city. I think that manchester city has been making pep guardiola feel disappointed with the management of club. The management of the club has been lying to him. The performance of city in UCL will be greatly affected by this scandal. You can read this to know more.

We know Pep Guardiola is a strict and disciplined person on the pitch and he doesn't hesitate to speak out what he thinks is not right and it looks like this problem will make him leave Manchester City soon.
