At the risk of losing the will to live by debating with you again, aside from Stones (let's say for argument sake he adequately replaced Kompany) and £13.8m Nolito I'd say the teams that started against Sunderland & Stauea were pretty much what we had available last season. The issues with MP's management started almost from the beginning albeit the deficiencies didn't truly manifest themselves until 12 months into his reign which coincided with the penny dropping with most managers that although Manuel had by far the strongest PL squad out of all clubs, he didn't have a Scoobie what to do with it.
By what you've posted, you make it sound like everything Manuel did was hunky dory up until February 2016. The fact is over the last 3 seasons we've regressed whilst you've vehemently defended that regression with an unprecedented blind passion for your man. Most of what Pep is doing now has been taught and drilled on the training pitch and even he let it slip in one of his press conferences earlier in the week that 'He wasn't here last season so he's not accountable for whatever bollocks went on before he arrived'. So Pep spending over £100m has had very little to do with our current brighter outlook and everything to do with us having a capable forward thinking manager as opposed to a fossilised 442 dinosaur.
The fans only wanted Manuel gone when it became very obvious to even his staunchest fan boys that he was out of his depth and our squad was stuck in reverse gear under his stewardship. That situation was brought about by one man and one man only........ Manuel Pellegrini! He had opportunities above almost every other PL manager and blew it big time and a PL title and 2 CoC's won't mask the wasted years under him.
We have a bright new future under Guardiola, but he's no messiah. I expect it will take time for Pep to stop the rot, turn our fortunes around and get us back to where we should have been and then to progress us beyond that. Even if we win squat this season, I doubt you'll find many fans complaining as long as they can see a viable plan and progress unlike the regression we've had to endure over the last 3 seasons.
I don't want you to reply, I just wanted to point out that just because Manuel has been removed and upgraded, it won't mask the deep disappointment many fans still feel over 3 wasted years which almost culminated with us being relegated from the Champions League. It will take time for our wounds to heal and your continued support and defence of the person responsible is akin to you picking at a scab and wondering why that wound is still puss filled and festering.
