Divide players into teams of 5. If you have a full-ground and 20 players, have 5 v 5 at each end. Three players from each team start inside a 10x10m square. One sweeper from each team starts on the defensive side (A), one forward from each team stands 30m away (B).
Start with players inside the square handballing and rolling the ball amongst one another (both teams).
On the whistle, the team with possession becomes the attacking team. Their aim is to get the ball to their forward (B).
The attacking team can use their sweeper (A), however this player is not allowed inside the square. The defending team attempt to effect a turnover (tackling optional).
The sweeper from the opposition can either assist their teammates up the field, or drop back into the hole and defend the forward.
Players must kick to (B). (B) attempts a shot on goal while players reset.
If there are extra players you make wish to make these the leading forwards who rotate.
Also rotate the sweeper with a player inside the square.
Optionally keep score of successful passes (1 point) and goals (1 point), or just score goals. After a few minutes, if you have games going at both ends, swap so the winners play one another.
