This is just going from bad to worse for Barcelona. And it's going pretty swimmingly for Real Madrid. The hosts nearly go 3-0 up only to see Sergio Ramos' headed goal end up ruled out for what looked like an imaginary foul on Gerard Pique. That doesn't matter much -- Madrid are so thoroughly in control that even Lionel Messi gets flustered, going in studs-up on Pepe. I didn't write that sentence backwards.
Aaand then there's a breakaway, with Ronaldo once again tearing through the centre. The only man nearby is right back Adriano, who was supposed to be playing on the left, and the fullback employs a rugby tackle to bring him down. Adriano's the last man back, and has to be sent off. So he is. Barcelona are down to ten men, and Sami Khedria nearly scores on the subsequent free kick, smashing a header straight at Victor Valdes. As things stand, it's 2-0 (4-3) to Real Madrid.
Alexis Sanchez is hauled off for Martin Montoya, by the way. Disastrous for Barca.
