I think because Burnley understand where they are.
Realistically they’re nowhere near good enough to compete in the PL. Yes Kompany’s style has put them in trouble a lot as well, but they’ve never looked like staying up; especially given their style in the Championship is just incompatible with the PL given their level.
Ultimately Burnley are ahead of schedule, they’ve made over 100M by being promoted, so being relegated isn’t the worst thing. They can go down, keep improving and investing, and come right back up even stronger.
I think he’s incredible but proof has to come over time. I think once he wins 2-3 Golden Shoes on the bounce people will actually take notice and give him credit.
At the moment its all “anyone would score lots of goals at City”.
