The thing with Bosz is his tactics are a bit naive..far too open and actually easy to break for the more cynical teams with enough quality of course.. but I admire him for such a bravery in the modern days where that kind of romantic way of playing football is rare.
Not saying you're wrong but out of curiosity, do you think the same about coaches like Guardiola or Ten Haag? After all, their approaches are quite similar. Always thought if anything, Bosz football is more suited to top clubs and if he fails at Leverkusen it is because tge players lack the quality to play his way (fortunately that doesn't seem to be the case).
