Liverpool owner John W Henry admits the popularity of football around the world still amazes him.
Henry discussed the power of Liverpool and the Premier League as global brands in a speech to the Boston Chamber of Commerce.
He said: "What's amazing for an American who is in the middle of the world's most watched sports league, the English Premier League is the scale of it.
"What Americans don't know is that when we play our rivals Manchester United the worldwide audience on television is just about a billion people. And that's for a regular season match, that's about nine times the size for the worldwide viewing audience for the Super Bowl.
"The relationship and rivalry between Liverpool Football Club and Manchester United is very similar to the relationship and rivalry between the Yankees and the Red Sox.
"And just as the Red Sox always seem to play second fiddle to the Yankees, Liverpool has similarly been frustrated by United since the Premier League replaced the Football League 20 years ago.
"So how can a rivalry like this attract a billion viewers? Both Liverpool and United are huge in China, Malaysia, practically every country in the world except the US."
