I follow this sport since the 90s and Italy for example never used them (and also USA for example), by the way it's not Poland's fault if Kubiak is what he is (dicks are everywhere). Maybe some day also in Italy we'll have a bad behaviour guy like Kubiak, at the moment (and at least in the last 20 years) we have not
I agree with most of what you have said. What you probably don't know or don't want to admit is that Italian players are famous for their verbal aggression at the net. The difference is that what Kubiak does is seen by many and what Italians say is heard only by the opposite team and stays among them. Are they really better?
