So how will Barcelona respond to going behind to their archrivals in El Clasico? From this evidence, they're going all out to get the goal back. They've had a lot of the ball since Sami Khedira's goal, and Lionel Messi's at the centre of it all. Unfortunately for the hosts, the rest of the team seems a little bit off. Andres Iniesta looks like he's getting ready for a run clear through on goal, but when Messi picks him out with a brilliant pass Iniesta lets the ball bounce off his foot, enabling Real Madrid to scramble clear.
Meanwhile, Xabi Alonso has made his mark on the game by coming in fairly late on Dani Alves, who is writhing around in pain Didier Drogba style as a result. The Real midfielder picks up a booking for his troubles, joining Sergio Busquets in the referee's naughty list. Nothing comes of the free kick.
