An article form the Daily Telegraph by a journalist who is also a youth soccer coach in England. American's won't get some of the references, but he has some important points that we can all learn from:

[...]the influence of such people at the top level, the place where it matters, is minimal. Go along to watch a game or training session at an enlightened youth academy such as Manchester United, Liverpool or Middlesbrough and it is like entering another world, a world less angst-ridden, less claustrophobic, less fraught. At United, parents sign a commitment to remain silent when they watch their children in action. Breach it and they are jeopardising their boy's chances of progressing.

The coaches, too, keep quiet. The result is the only voices that can be heard are from the kids, having the time of their lives as they play their small-sided games, their skills flourishing with every back-heel and lollipop. Nobody raises their voice, nobody rants, everybody just has fun. And this is at a club presided over by Sir Alex Ferguson, the world's most competitive manager.
