Such is the tragic of the goalkeeper - he can be brilliant throughout a whole match (or tournament in this case) - one single mistake destroys everything. I was thinking about Harald Schumacher all the time before the final (i.e. BEFORE Rethy Béla mentioned it) - we even discussed this while sitting in front of the TV during the match itself - if Kahn will be beaten, it will be by a massive blunder of his. Could we know how cruelly we would be proven right... :-(
P.S.: If he was hurt and he knew it, why didn´t he had himself substituted? That´s part of greatness too, knowing when one can´t be of service to the team any more.
