Kids at that age are for the most part interested in taking the ball themselves and don't look to pass. The problem is that by drilling that nature out of them, we create these players that only look to pass in just a few years -- I've seen it happen over and over again. Rather than drilling it out of them, why not create some SSGs that encourage passing instead. One I love is everyone's a striker - where a player can only score once until everyone on the team has scored a goal. Another interesting one I found but haven't tried yet, is ghost - one player is the ghost on the team and the only one allowed to score a goal. Yet a third that seems to be really challenging, slow soccer, where no one is allowed to run. In these SSGs, you don't prevent players from taking on 1v1 situations, but you force the players to think about the rest of their team, situations where you can't do well by just looking down at the ball. The added benefit is that the players learn how to do this within the context of the game, making it easy for them to apply it during the game. I'm coaching the same age level here and most of the players on my team are very comfortable winning the ball, holding it up against defenders and beating multiple players 1v1, 2v1 and sometimes 3v1. It's a bit embarrassing in comparison to our opponents. The players are slowly getting better at moving off the ball and taking advantage of spacing for passing/receiving. That being said, they still have a long ways to go on their ball control, dribbling and 1v1 skills - things that would be terrible to drill out of them for the sake of making a few more passes. Note: the tactic that worked when it came to teaching the players how to redirect the play using a back pass was simply to show them the movement using a white board drawing. They kept getting trapped during practice SSGs, so at one point I stopped the game and drew out the suggestion. They took it and ran. So, try providing suggestions and let them figure out how to apply them.
