It's Messi vs Ronaldo, it's Catalonia vs Castilla. It's the nation against the state, freedom fighters vs Franco's fascists. It's majestic goals and mesmerising skills, red cards and bench brawls. It's the best two teams on the planet going face to face and toe to toe. It's more than a game. It's a war. It's Barcelona vs Real Madrid...Only, it's...
