Every December three clubs you've heard of (this year it's Barcelona, River Plate and Club America), and four more you probably haven't, compete in the Club World Cup. It's a poorly designed competition that takes the winner of each Confederation's Champions League (or equivalent) and puts them into a mini-tournament. Barca and Plate will only need to win two games to claim the title. For teams in CONCACAF, the AFC and CAF it is an opportunity to play for an actual trophy against the greatest clubs in the world. For CONMEBOL and UEFA sides it is a short diversion from meaningful competition.
