Manchester United is planning another tour of the US next summer. Obviously, it's all about the money. Whereas the average Major League Soccer game can attract on average just 14,000 fans, Manchester United were able to average 67,848 during their tour there this summer. Americans just won't settle for second best, obviously. They don't want to watch inferior clubs. With all the other sports played in the US, the professional leagues there are the best in the world. The Soccer league is, however, clearly inferior to any major European league.
This article aslo has a lot of details about up and coming American stars who have signed with Premiership clubs. And, interestingly, a quote taken from a Washington Post article by Manchester United's youth director who believes the US will win the World Cup England does. Maybe it will happen when Freddy Adu leads the US team out onto the pitch.
