There's another great chance for Barcelona to take the lead. From a long free kick, Sergio Busquets rises highest, guiding a header juuuust over Iker Casillas's crossbar and onto the roof of the net. He probably should have scored there, especially if Pep Guardiola's face on the sideline is any indicator. It says something that three of the four best Barcelona chances of the match have come from headers, but I'm not entirely sure what that is. Perhaps they'd be ok against Stoke after all?
Real Madrid are doing their utmost to put pressure on Barca, but they're mostly running into dead ends and losing the ball far too easily, which is making it very difficult for the hosts to both attack and defend convincingly at the same time. Now that Barcelona have their away goal, they're less inclined to leave Real space for the counterattack, so things aren't looking too good for Jose Mourinho and company right now. Still 1-1 though, and anything can happen.
