My opinion? No. He's still an excellent manager and coach and he knows a lot about the game and isn't scared to experiment. But he still needs to adapt and he needs to get in new players. If I was Pep, I'd sell all my players in the defense. They all suck. Otamendi, Zabaleta, Kolarov, Clichy, Sagna and even John Stones. They make so many mistakes. I don't know why that is, maybe they don't get Pep's system.
Beside all the result, i'm agree with you Pep still an excellent manager and coach, but City management should giving Pep a warning and a new target, what target should reach for this season, I think is quite hard for City to still have a
change chance win the EPL Thropy, maybe the best target for now is ticket to play in Champion league next season. City need new player to improve they games or don't use player who always make a mistake in the match, and giving trust to backup players to play.
