Real Madrid will probably happy to end the game now, thinking about it. Barcelona are keeping the ball and just waiting for the tired home team to make a mistake so that they can pad to their lead. If 1-0 would be bad, 2-0 would be disastrous - they can't afford to go to the Camp Nou having to make up a two goal deficit which... oh.
Barcelona are 2-0 down after a beautiful goal by Lionel Messi, who just ran through five Real Madrid defenders to plant a shot past Iker Casillas and in at the far post. That is absolutely magnificent (watch here), and I think it probably wraps up the whole tie. Goodness, that was impressive, although I have to say that I think it was probably going wide before Sergio Ramos got a touch on it right at the end. Whoopsies.
