Not only Pep Guardiola but Manchester City as a club are beginning to lost momentum, I think it's an era coming to an end because for Manchester City to seat in such position in the beginning of a season means that something is not right some how, if I'm to be Pep Guardiola I'd take a shot break to cool off the tense.
I think I will have to believe that part that you said, you think it's an era coming to an end, initially I just thought last season was a bad season for him but with what's happening now in the team it really seems that it's an era coming to an end. Maybe it's too early on the season to conclude but seriously, this City team was not the Manchester City team we all used to know under Pep
It's hard to say that because even though Pep Guardiola is a great coach and it has been proven in several different teams, but on the other hand, there is no other reason for Manchester City's current slump except Pep's mistake in the strategy he used, even though they have made many changes compared to last season, nothing has changed so I also think it's time for Manchester City and Pep Guardiola to part ways.
