1.  Break your squad into 2 equal teams.  The ideal number for this game is 6-8 players, 2 teams of 3 or 4 players.  Should you have more players consider having 2 coaches and 2 sessions running at the same time.  We will assume you have 8 players, 2 teams of 4 players.

2.  Get the players on each team to have a number e.g. 1 to 4.  On the attacking team, player 4 will be the substitute player.  On the defensive team, players 3 and 4 will be substitutes.  The substitutions can be made by rotating the players based on their number e.g.  1, then 2, then 3, then 4.

3.  Allow the first group of players to go up the pitch.  You can either change players every time they go up the pitch or allow one group to go up the pitch and back, then change players.  The second option allows the coach to have more interaction with the substitute players, but is unnecessary to begin with.

4.  Conduct the game for 5-10 minutes maximum.  The players will take time to get familiar with the game, just let them play.

5.  Stop the group and focus on only 1 coaching point.  The stoppage should last no more than 2 minutes.
During a game of touch, a coach will only have 2-3 minutes to interact with the players, so get used to that time frame.
The coach will only be able to cover 1-2 points in attack and defence, so again, get used to being brief and to the point.

6.  Conduct the sessions over a number of weeks e.g. 12 to see the full benefit of this game.

7.  Do as many of the mini-sessions as you need each week.  As an example you might set aside 20 minutes each week and only cover 2 min-sessions.
