No outside players can step into the gaol zone. 3 lines of players, 3-4 in each. They now play a 2v1 sit. On the other goal. If the winger misses his cross, he is the defender.
Play starts again.
You can switch lines if you want. Coaching Try to score on every chance you get. These things decides games. I think the drills are good. The Warmup also cleverly integrates the topic of the session.
