According to the annual ranking released by the London-based consultancy company Brand Finance, FC Bayern München has passed Manchester United for the most valuable brand among the world's football clubs.
With an increase of €51 million ($66 million) compared to the previous year, coupled with a €20 million ($26 million) loss for the former #1 from Manchester, the Bavarian giants leapfrogged into the lead with a total brand valuation of €669 million ($860 million). It appears that playing a major role in the top European competition has significant influence on this value, with Bayern making the Champions League final 3 of the past 4 years (and finally winning it this year, WOOOOHOOOO!), while United did not make it out of group play, or was eliminated early in the knockout stages.
Real Madrid and Barcelona are in third and fourth, but with a rather large gap on the two leaders.
Here is the story from the FC Bayern website. It's interesting to note that this ranking was completed before this year's Champions League final win, which can only add to the global appeal of Bayern.
Keep in mind, this is not the actual value of the club (where Bayern is in 5th place), but the value of the brand, meaning the ability to generate money on their name and reputation.
