Gelson Fernandes Goal Versus Spain

Fernandes, the Swiss forward, scores the game winner for the biggest upset of the 2010 World Cup so far. For me, I’m wondering if Iker Casillas could done better?

For me, a keeper has to make one big game winning save per game. However, after a few looks at the video, seems like Casillas comes out well but the ball deflected back off Eren Derdiyok, who made the initial run on goal.
