Sergio Busquets gets away with a really meaty challenge in the 14th minute as Real Madrid players again berate the referee asking for a yellow card for the Barca midfielder.
Barcelona does not look comfortable at all early, it's a big difference from Saturday's meeting where Barca controlled the game until the very end. Mourinho has clearly put a more aggressive plan in place for his team today and it's making a difference as Madrid is getting chances and preventing Barca from dominating possession.
Pepe gets away with a nasty studs-up challenge on Lionel Messi. Pepe probably should have been shown a yellow on that as his studs dug right in to the Barcelona forward's ankle and foot.
Barcelona earn a free kick about 25 yard out, but take is quickly rather than working the set piece opportunity. The decision yields no result as Barca are unable to generate a chance and eventually lose possession.
