Ive seen City play, considering the average level of PL teams, it is not surprising. As for attacking football, Bayern played such a boring style under him, alot of fans were not satisfied, in his last year Barca games were so utterly boring, i fell out of excuses why anyone would call it attacking football. Yes, he brings his ideas in, they work for a few seasons, then other coaches find proper countermeasures and you will end up watching 90 minutes of boring sideways passing and trying to walk into goal with ball.
Ive said it many times that I enjoyed our football alot more during Luchos treble season, but sure, that is just my opinion.
Anyways, I am sure there are many genius tacticians in the world, but they have been not lucky enough to get a chance to lead a golden generation or then have 300 mil getting any player they want.
