I think his style works if you have talent (because talent can play any style) or if you have no talent (where you might get more space against better teams chasing Ws). If just mediocre (which is what Belgium is) its terrible.
I guess the only good thing about going to 48 is that North Africa is developing a bunch of fun players but because African qualifying is so brutal (1 loss=death) everyone is so defensive and maybe they'll be able to get more freedom to play free wheeling footie.
