NO
Like it or not, Zidane was still one of the best players in the Cup. One red card shouldn't change that. If Thornton had a Game Misconduct in the last game would his Hart be taken away?
BTW, that same investigation could strip Italy of the World Cup. Is either likely to happen?
Any player who misses an opportunity like that in a Championship game will react like that.
Remember Stevie's reaction when he missed a perfect opportunity in OT against Carolina in 2002?
Remember Shanny when he missed the open net with a minute to go against Colorado in Game 5 of the 2002 series?
Were their games being "shut down?"
For those who haven't seen this, take a look at Materrazi's history.
