Peter Singer says it:
[German goalkeeper Manuel] Neuer missed a rare opportunity to do something noble in front of millions of people. He could have set a positive ethical example to people watching all over the world, including the many millions who are young and impressionable. Who knows what difference that example might have made to the lives of many of those watching. Neuer could have been a hero, standing up for what is right. Instead he is just another very skillful, cheating footballer.
I don’t have a problem as such with Germany winning, as I think it was the better team, but the way Germany won the match definitively put a sour taste to it. Just like “the hand of God” made Argentina questionable world champions in 1986.
Update: The goalkeeper’s name corrected.
