Momentary Madness?

What a tragic way for Zidane to end his legendary career. I really wanted to see him score the winning goal and raise the World Cup once more, for the Grande Finale of his illustrious career as one of the greatest midfielders of my generation. But fate had another score for him to settle. It was very upsetting to see him using his head instead of his magical feet. What I can't figure out is what was said to bring out the demon in him? Perhaps the spirit of Hitler spoke from the infamous Olympic Stadium once more - bringing out the worst from the best of people. Spooky.
