Personally for me - this is Pep's last season at City.
He is trying things & younger players that just dont work as smoothly as last season because he just doesn't care as much after winning the treble last year. He did his job and he knows it. He is going to give it a go again with the momentum of the club but with younger players like Foden, Doku, Bobb etc because he wants to leave City with a good group of younger players (this is why Mahrez & Gundogan etc left IMO).
Then Klopp has already said he is leaving this season aswell.
IMO, the next season is going to be very open almost like Leicester City title win season because the chances are that only really Arsenal will have the same group of players and manager to be favourites for the title (which could happen this year making them instant favourites for the coming year).
I say this because I think we genuinely might have a chance of going for the title next year because this could be Ten Hag's 3rd season in a time when the league itself is going to be weakest of the past decade. (
@Adnan made an excellent post about how Ten Hag's transitional team was nearly there & arguably only needed the correct high line CB's to have a complete competing first 11)
We either stick with Ten Hag and go for the title, or we go for someone who is automatically the best options in the world under Pep & Klopp as soon as they leave.
Managers like Nagelsmann or Potter for example cant win the title next year because they are more likely to focus on building of the team rather than instantly getting the best out of their players.
If we want to win the title next year though - the managers are going to be less eye catching because they are much more likely to be short term. These are more in the mould of Simeone, Conte & Ancelotti IMO (maybe Tuchel but im not sure) - managers that come in to a league that has just lost Pep & Klopp and arguably instantly become the best in the league through experience and aggresion. I personally hate Jose for example, but if he was never hired post LVG then i think even he could have been an option to come in a season without Pep & Klopp to scruff out a quick short term title win just to provide some context because he wouldn't struggle that hard against Arteta's Arsenal being the title favourites.
Either stick with Ten Hag and go for the title competing with Arteta's 5th year vs Ten Hag's 3rd - or completely go for those aggresive experienced managers that have been able to compete with Pep & Klopp during their career's at different times but maybe lacked their level of consistency & go for it as soon as they leave.
