How could Zidane be tickled so much that he did what he did? The foul was not only unnecessary, but it proved critical at the moment and in the game overall, because Zidane was needed to make one of the penalties for France, and that ended up being the big difference between the two teams in the end.
It was an unbelievable action by Zidane, and one which will tarnish his entire career for a long long time. People will now not remember him for what he has done in the past, but what he did to effectively lose the World Cup for his country.
Sad end to the competition, to his career, to the finals.
But a great game to watch otherwise.
