Who said there are no youth teams playing good soccer/football in the United States? Who said kids can't learn how to play possession soccer at a young age?
Check out this State Cup Semi-final match between two Southern California clubs, Barcelona-USA and Arsenal FC. A clinical display of possession soccer that the real Barcelona club would be very proud of. These teams have loose ties, if any, to the clubs in their team names - Arsenal and Barcelona, as far as I know.
The man connection the two teams have though is in mimicing the style of play of the these top clubs, which they are doing very well. Take a look the long series of passes the teams put together, how they switch the ball from one side of the field to the other, and how they keep the ball. Remember, this is U11 youth soccer.
