Madrid - European champions Real Madrid are the world's most valuable soccer club for a third straight year, according to a Forbes poll released on Wednesday that showed the average value of the top 20 teams rose 11 percent over last year.
The Spanish club's value fell five percent to $3.26 billion but their $746 million in revenue, the highest of any sports team in the world, was enough to keep them top of the list, Forbes said in a statement.
Barcelona ($3.16 billion), Manchester United ($3.10 billion), German champions Bayern Munich ($2.35 billion) and Manchester City ($1.35 billion) rounded out the top five.
Rising television and shirt sponsorship revenue helped drive the average value of the top 20 clubs to $1.16 billion, a staggering 84 percent jump from five years ago.
Eight of the top 20 teams are from the English Premier League, which Forbes credited to both a rise in the British pound relative to the euro and U.S. dollar and a lucrative new domestic TV deal starting from the 2016-17 season.
Serie A champions Juventus ($837 million), AC Milan ($775 million), Inter Milan ($439 million) and Napoli ($353 million) are the only Italian teams to crack the top 20 but none were higher than ninth place.
Forbes said the once-great Serie A brand has been undermined over the past decade by match-fixing scandals, antiquated stadiums, rising debts and a decline in talent on the pitch.
