2. Real Madrid—Spain

The Spanish giants are the most successful team in Spanish football and was voted by FIFA as the most successful football club of the 20th century, having won a record 31 La Liga titles, 17 Spanish "Copa del Rey" Cups, eight Spanish Super Cups, a record nine UEFA Champions Leagues, two UEFA Cups, one UEFA Supercup, and three Intercontinental Cups. Real Madrid was a founding member of FIFA and the now-defunct G–14 group of Europe's leading football clubs as well as its replacement, the European Club Association.

Right down the blades of grass at the Bernebeau, Madrid epitomises perfection.

There is no seperating these two world football giants.
