I don't meant to disrespect Guardiola but hope you know that era do comes to an end and there are stages where you quit to respectfully keep your hard work for history to look at. Guardiola is a successful coach but the things that are happening around him is among things that made Manchester City fell of, no matter how string minded person you are, in any career you build and you lose your family in the process, it will definitely affect you psychologically.
Yes, I agree with you. The Pep era has begun to fade out. We certainly remember how the Mourinho era used to be. There are times when a coach is no longer good, and slowly begin to fade over time. There is Cruift era, Van Gal, Capelo, Mourinho, and the last one is Pep. Because Eventually their strategy he was implement is already to read, and can not be used again over time. Even a small clubs, who are not compete on top league already know how he implement his strategy. One of the predictable things is how dizzy Pep when Rodri is injured, the opponent know how to stumble the defense because the opponent know who is key of pep strategy.
