Yea apparently MM said that he wishes death upon him(zidane) and all of his family, and to go *####* himself. Not something I would headbutt someone for, maybe slug him a few times with my fists, not my head. Not something to go out on Zinadine.
if i was ZZ i would have waited till after the game and give him a right good gong over, it was dam right out of order what ever he said and spoils the game IMO .
