Think these guys are sick of each other yet?
Barcelona have already all but locked up the La Liga title.
Real Madrid just won the Copa del Rey at the expense of Barcelona.
Now that the two hated rivals have battled it out for Spain's two biggest domestic trophies, they get to hash things out two more times to help decide who will hoist the most coveted trophy in all of Europe: The UEFA Champions League.
It will conclude a wild 18-day stretch where the two historic giants battle for an unprecedented four times. Americans may struggle to grasp the gravity of such a stretch, but imagine if the New York Jets played the New England Patriots for four consecutive weeks. Then, add in a century's worth of bad blood stemming from not only on-the-pitch battles, but deeply-rooted political and social tension, too.
Oh, and they're widely regarded as the two best sides in the world. They each boast two of the best attackers in the world in Cristiano Ronaldo and Lionel Messi.
Stay tuned, we'll keep you up to date with all of the latest anything and everything Barcelona- and Real Madrid-related.
