No you're building a strawman.
If you want to talk about Pep's performance then fine. So do I and presumably FI. BillyShears has a whole podcast where he's critical of Pep and in fact gets slagged off for being TOO critical by people.
The thing that pisses me off is that some people have a starting place in their logic that he's wank. Bill's constant sneering towards who is seen by the non-City friendly media as the best manager on the planet is ridiculous. Same with many others. This "HE DOESN'T KNOW WHAT HE'S DOING, HE FLUKED EVERYTHING AT BARCA AND FAILED AT BAYERN!" is also ridiculous.
The difference between us and them is that we generally start from a place that Guardiola knows what he's doing due to the about fifty fucking trophies he's won in 7 years of management. We think that if something does wrong then it's worth thinking about what he was trying to achieve, what did or didn't work, and plan from that. What we don't do is say his entire system of football is wrong and here's what he should have done instead gleamed from years of experience I have about football from being a bricklayer in Blackley.
For the record, people used to say the exact thing you've said about me when I talked about Hughes, Mancini and Pellegrini. In fact I had arguments with Billy over Mancini and FI over Pellegrini. These people are at the very very top of the game that's inhabited by millions of people. You don't get there by being a clueless buffoon. You presume that they know what they're doing as a starting point and jump off from that.
Doing the opposite thing where you presume he doesn't know what he's doing is what gets me sneering and looking down my nose at people. This guy isn't just talented, he's the top 1% of the 1% and has the trophies to prove it. He deserves to be given a bit of respect for that.
