funny, my boss ask me the same thing yesterday when he see the dutch players arguing with the uruguayans when de zeeuw collect the boot to face...
i think by and large men does cuss out each other in they native tongue on the field. As for the referees, before the game they acquaint themselves with common phrases in each language to communicate. Also, I think they use common english phrases re football that everyone would understand on a field, and they even have a handbook of curse words in each language so that they can pick up on it on the field.
but i does really wonder though how men does communicate. Like in them scruffles on the field on TV when men trying to peace it out, it does look like men understanding each other so i not sure myself.
