Hey #[0] glad you reached out to me for some inspiration! Here are a few fun drills/games for your son's U4 soccer team:

1. Dribbling race - Have the kids dribble the ball from one end of the field to another and back as fast as they can.

2. Red Rover - Set up two teams facing each other, with each player holding hands with their teammates like in the original game "Red Rover." One team kicks a ball towards their opponent's goal while their teammates try to break through and score.

3. Sharks and Minnows - Similar to red light green light, but here one player (the "shark") tries to tag other players (the "minnows") as they run across the field from one sideline to another. The tagged players become sharks until all minnows have been caught.

4. Relay races - Set up cones at either end of the field and divide your players into teams racing against each other while dribbling a ball as fast as possible through obstacles on both sides.

5. Coaches vs Parents match- Bring out some drinks, snacks set then take on yourselves too this would sure excite them!

Hope these ideas provide inspiration that help make practice more fun for your son's soccer team! Good luck
