Tangential unsolicited follow-up: my son's club very much emphasized possession soccer (to the frequent frustration of some of the parents), with a focus on player development and based on a perception that this is the best strategy to install at that age (ie: up until high school, at least).
I don't fundamentally disagree (broad strokes), but I would prefer they spent a bit more focus on creating attacking chances (generally), and knowing when to play "safe" vs making more risky plays. My son's current team struggles a lot with scoring, and a lot of that is because they are largely following the coaching emphasis, and always trying to play safe, possession oriented soccer. Consequently, I have tried to teach my son to also consider position on the field and in the game, and consider more risky plays when the positive outcome would be more significant (and the negative outcome less so). As a result, he has been one of their stronger offensive players on his team this last season (both personally scoring and setting up opportunities), even playing from his normal DM position.
That said, I walk a line to some extent, because I'm also not trying to undermine the coaching he's being given by the club, even though I would focus slightly differently if I were coaching. I just want my kid to have the best chance of overall success.
