Which Sporting event attracts the most viewers worldwide- The Champions League or Superbowl?

I would almost certainly say the Champions League....maybe you can't find statistics for out side the US because nobody outside of it watches it. OK that's obviously not true i'm sure there are small communities who do tune in, but American Football is hardly the phenomenon it is outside the US. Football (Soccer) on the other hand is played all over the globe and has many different teams, from many different nations competing in the Champions League. The sheer diversity of the nations involved would surely lead to more people watching, not to mention non EU nations who just want a chance to watch some of the most famous footballers in the world play. Asia especially has a strong interest in Football and they comprise a huge amount of viewers, I don't believe they have any interest in American Football though, just baseball.
