I got this believe that the case would be in favor of City and if it requires them to spend heavily to get away with the charges then they're very much capable of doing so since they're backed by oil rich owners. Well whatever the case may be I think it's not going to stop Pep Guardiola from leaving City soon my reasons are that he's achieved everything achievable in the league and has set lots of records so he'll want to try another experience which is coaching a country team and winning trophies like the World Cup or so and even though Pep Guardiola decides to continue at City after this season, I doubt if he'll stay more than a year, he'll definitely sign a year contract then probably win another EPL trophy then resign like Klopp did but come to think of it, 300 million is more than enough and a great advantage to any coach that succeeds Pep but City should take their time when it comes to selection so they won't make same mistake Manchester United did after Sir Alex Ferguson's retirement.
I agree that spending money doesn't equal to winning, what Pep did was spending money too, but other teams did the same but couldn't get the same results, which means that it is not just about the money, it is about other stuff as well.
This is why I think Pep really should consider this decision if he wants to leave or not, and if he leaves, then City should really consider who to get next, they can't get some regular level manager if they want to keep this going. Pep is known for getting players for a lot, but he gets players that will fit with his system perfectly, and he wins with them so it is justified for him to spend that much. He is not like ETH who spends hundreds of millions every single year and has nothing to show for it in return.
I believe that Pep leaving City could be one of the worst things that could happen to City, and they need to focus on getting someone like Xavi who would be playing around the same system and it would really benefit them. They both come from the famous Cryuff Barcelona system backgrounds and they are both making their teams play that way, plus Xavi is not hired so far by anyone, and if it stays that way, at the end of the year they could make that work.
