Have half of your players (A) with ball scattered on the outside of the square.
Have the other half of your players (B) stand in the middle of the square, without ball.
Execution:
Players B move around the middle area and by calling ask for the ball a players A.
Player A plays the ball to player B, who does the desired action and passes it back to player A.
Player A must always stand on his toes to make the pass.
Player B must accelerate slightly when asking for the ball (to outrun a defender in a normal game).
The tempo is medium to high so you have to switch within 45 seconds and 60 seconds, B to outside, A to inside. You can switch multiple times and have the players make different actions.
quality:
Each pass should be high quality and accurate.
Players in the middle must speed up their pace when they get into the ball.
Players on the side are always on their toes.
As the difficulty increases, the quality must remain high.
All balls must stay in the square.
Don't forget to encourage successes!
Progress
Build up skills, e.g. 1st time for each group hit 2 times
Then 1 only hit once
Then hit only once and play back to another outfield player
Add a passive defender, the players inside must accelerate to shake off the defender.
