It's a shame that the Zidane ended his career on such a classless note. As soon as I saw the replay of him head-butting the Italian player, I said, "If any of the officials saw that, it's got to be a red card!" And it was, no doubt about it. Even if the Italian player was taunting him, Zidane made a terrible mistake. He had an opportunity to end his career like Beckenbauer, and instead wasn't even on the pitch when his teammates collected their second-place medals.
More encouraging was the show of good sportsmanship between the two teams' goalkeepers before the penalty kicks began. Also, I think the match overall (unlike most of this World Cup) was officiated excellently, with the players being allowed to play and to decide the game on the pitch. You hate to see a World Cup decided by penalties, but this one was so equal that it was possibly inevitable.
