so we won our first scrimmage...still plenty of work to do
Congratulations. I hope it´s the first in a long row.
Something else I thought of are Set Pieces. Free Kicks, Corners, Throw-Ins...they often decide over win or loss. I suggest you create certain plays that you train with your team. These situations often get out of control, so it´s important that your guys have a plan they can rely on and execute. It´s not a sexy way to win the game, but a very effective one.
For Corners, one option is to cross the ball long into the box for headers, another is a short pass to someone who then crosses the ball, or simply drives into the box himself. He could also play it to a teammate who lurks outside the box who shoots it from distance. Make sure that everyone knows his role. If your player plays the ball long into the box it´s a good idea to drive the ball away from the goal, as it´s much easier to head a ball that´s coming your way instead of one that drifts away from you (I hope that makes sense).
It´s also important to assign your guys a fix opponent for the other team´s corners. Normally, your defenders should take care of the opposing strikers, while your strikers stick with the opposing defenders. Your Goalie has to get the ball, and everyone else should "box" out.
For Free Kicks and Throw-Ins, you´ll have to watch some games, so you can pick some set plays up, if you haven´t already, like stepping over the ball to let someone else shoot, passing the ball low to a quick attacker who crosses or drives, high crosses to your deepest striker, and so on.
