This is exactly what Pep is trying to do,he is a man that loves to make history,and if he determines to do that,I don't think anybody in the Champions league has the ability to win them except Arsenal.
Are you trying to say Arsenal is the only team that has the ability to defeat Man City?
Man, I even assume if Arsenal has no chance to win Man City in UCL. Real Madrid and Bayern Munich are 2 teams that possibly defeat Man City. Guardiola is easy to understand how to deal with Arsenal because they are in the same league (EPL). Guardiola must be very often to analyze the weakness of Arsenal. But for Real Madrid and Bayern Munich, it won't be easy to know the weakness of these teams. They are 2 specialist teams to win the matches in UCL, they also have strong squads, and they are in the different leagues.
They have their best players back on the field which is Debruyne, Haaland,Rodri and Benardo Silva.
If City can win back this tittle,then I would know that City is really the best team in Europe at the moment,and I also think if he wins this champions league,he will resign from the club.
Man City has everything to win again UCL title this season. They have strong players, they have an experienced coach. Some players ever got injured, but they have recovered now and ready to give their best performances. If Man City plays with a full team, Man City will be superior against any team in UCL.
There is no reason that Pep Guardiola to leave Man City. Moreover, if Pep Guardiola wins again some prestigious trophies, he probably will have a contract extension in 2025. Winning UCL isn't the reason to leave, it is even the reason to stay longer. Man City will appreciate his achievement by extending his contract for more years.
