I admire Zidaine, he was the one we watched in the United States, especially during the world cup. The head-butt was classic, and he shouldn't been red carded for it. After all, Marco talked about his mother and sister in a negative way. Otherwise, France would have won the World Cup. In the end, for Zidaine, the head-butted towards Marco Materazzi in the 2006 World Cup is my favorite.
