Real Madrid and Atletico Madrid will go head-to-head later this month to decide which football club is the finest in Europe but, when it comes to the bottom line, there is only one winner.
The city rivals will battle it out in the Champions League final on May 24 in Lisbon, but Atletico look to have their work cut out given the financial disparity between the two clubs.
Nine-time champions of Europe Real top a Forbes list of the world's most valuable football teams, with Los Blancos reportedly worth $3.44 billion.
The Santiago Bernabeu stadium team, which boasts the talents of FIFA Ballon d'Or winner Cristiano Ronaldo, posted a revenue of $675 million for 2012-13, with an operating income of $172m.
