No the US will never develope a world class player who os striclty born and raised in the US and will never do anything in the World Cup for one simple fact.  Soccer in the 7th or 8th choice for sports kids play when their young and continue to play as they grow.  All of the best athletes from this country play football, basketball, baseball, hockey, lacrosse, nascar, even wrestling before they play soccer.  While in the rest of the world soccer is 1st or 2nd.  Imagine if in the US people like Devin Hester played soccer on the wing or what a center back LeBron James would make.  But our best athletes focus on other sports so the US will never develope a great soccer talent remember Adu was originally from Ghana wear soccer is the most popular sport.  Altidore will eventullay become the next Landon Donovan or Brian McBride he may have some succeess over in Eupore but will never be his teams best player as long as he plays in a top teir league.
