Soccer is not the top-watched sport in the United States, but it is everywhere else, meaning it's worth big bucks. Consider this: In our rankings of the world's 20 most valuable teams, England's Manchester United is No. 1, worth $1.2 billion. Compare this with the Washington Redskins football team in the U.S., which we've valued at $952 million.
With values like that, it's no wonder that the clubs have global powerhouses such as Nike, Vodafone, Reebok, Siemens and General Motors (through its Opel division) as sponsors.
Our coverage includes not only a table ranking each club by valuation, but also spotlights each team individually; the billionaires behind the scenes; a profile of the marketing-savvy English club Manchester United; and polls and discussions so you can tell us what you think of our valuations and the teams.
