How Real Madrid only have one goal in this match I don't think anyone knows. It's brilliant play from the substitutes, with Gonzalo Higuain driving at Barcelona's defence before releasing Kaka on the left, who skips into the penalty area and drives a shot towards the near post. Victor Valdes should be beaten, but he somehow isn't, managing to divert the ball with his leg over his shoulder, across the face of the goal, and out for a goal kick. At this point, Madrid can't buy a goal.
At the other end of the pitch, Barcelona nearly make it 4-1, with Andres Iniesta's run sparking a minature game of pinball involving Iker Casillas, his centre backs, and three Barca attackers. Ten seconds of chaos ensues before the ball miraculously ends up in Casillas's arms, and Madrid can clear. Not that it'll matter, mind - 3-1 isn't much better than 4-1.
