Two months after Spain's biggest football match was postponed due to political unrest, Barcelona host Real Madrid on Wednesday in a La Liga fixture that could have a huge impact on the title race and will take place amid fresh protests. Lionel Messi's Barcelona head the standings with 35 points from 16 matches, with Real Madrid only trailing on goal difference. Barca lead the head-to-head results in competitive matches with 96 wins to Real Madrid's 95. Real Madrid captain Sergio Ramos will become the player with the most clasico appearances should he line up at Camp Nou. The Spain defender is currently locked on 42 appearances in Europe's most anticipated match alongside Manuel Sanchis, Francisco Gento and Xavi. Spain will deploy a large-scale security operation involving 3,000 personnel at Camp Nou, when the likes of Messi and Ramos look set to share the limelight with Catalan separatist protests. Tension in Spain's north-east region boiled over in October when demonstrations and riots caused the original La Liga fixture between Barcelona and Real Madrid to be postponed.
