If you're captain of your team you gotta lead by example, especially during the most challenging times, not get sent of for a headbutt you made to settle some personal grievance with a bloke like Materazzi.
If it hadn't been for that (call it choking, losing your cool, whatever), France could've still gone out on pens and Zidane would've still been my choice for player of the tournament. But seeing as things went the way they did, Canna was the real capitano.
