I get the overall point you're trying to make, but man you're talking some fucking garbage to get there.
I think your unsubstantiated point, which has no empirical backing and flies in the face of facts, is what is garbage. And I think you now realize that fact, which is why you resorted to what amounts to an ad hominen.
And I don't think it is ridiculous to say that part of the reason we beat Man City so many times in a row is that we had a mental advantage over them heading into matches. Once we did lose to them, which was inevitable at some point, and the mental advantage was lost, we were always going to struggle to regularly beat what amounts to a superior team, particularly since Man City is now more consistent and established as a top 4 side.
