Exactly that is where Pep Guardiola got it wrong by not signing enough players last summer transfer window, this had resulted to their poor runs, though he had some few signings like return of Gundogan from Barcelona and signing of Sarvinho, I believe Pep Guardiola thinks that he has a formidable squad with depth not considering injuries that might hinder his squad, now a handful of first team players are out injured among them include Rodri, Ake, Akanji and Stone those players would have make a positive impact on the team had they been fit unfortunately Pep Guardiola didn't have perfect replacement for them and it obvious some of the squad players are getting old thus wouldn't play optimally players like Debruyn, Silva and Gundogan.
For me, Pep made a huge mistake in that regard. To be honest, the Golden Ball winner, or supposed Ballon d'Or winner, does absolutely nothing, he just watches others go and conceive goals against him. He just watches. That's how it looks on TV. I don't understand, but for me he's not a good player. However, Pep is paying the price for him. City's solution is to reform the team, to come up with a different strategy. I find it strange that Pep hasn't reformed himself. If he continues like this, the defeats are going to be much more constant and it's a shame. Honestly, the most epic match was the derby against MU.
