Attack a 3v2 at speed before the defence recovers, and switch from attacking to defending the instant your attack ends: two defenders press and cover against three fresh attackers.
Use the penalty area end of a pitch: the real goal on its goal line, and a second full-size goal facing it just past the D, about 26 m from goal line to goal line, with a keeper in each. Mark the sides 28 m apart: on each side a pole in line with each goal and two markers between them. Split the outfield players into two teams of six (two groups of three). Each team waits on the goal line beside the goal it defends: one player in a central spot just outside the post with a ball, and one in each wide spot, the second group a step further out. Start with three from one team attacking two from the other. The moment the ball goes in the goal, out of play, or the keeper saves it out, the next three of the team defending that goal come on at once, already spread: the player with the ball central, the other two wide, and attack the other way. Of the three who just attacked, one goes off and the other two stay on and defend. The one who goes off is whoever is furthest from the new attack: when the central player plays out to one side, the attacker on the far side leaves and jogs back up the side to his team's end. The two who were defending are already beside their own goal, so they simply walk off, picking up the ball on the way and giving it to their group's central player for the next attack. It is always 3v2. If the defenders win the ball or the keeper holds it, the attack is over: play it out and the switch happens as normal.
This is a continuous transition game seen in professional training: always three attackers against two defenders, both ways, with no stoppage between attacks. It is played at the penalty area end of a pitch, between the real goal and a second full-size goal facing it just past the D, about 26 m apart, with a keeper in each. Each team waits on the goal line beside the goal it defends, in a central spot beside the post and two wide spots, so the next three always come on already spread.
The rotation is what makes it work. The moment the ball goes in the goal, out of play or is saved out, three new players of the team that was defending come on and attack the other way. Of the three who just attacked, two stay on and become the defenders, and one goes off. Who goes off depends on how the new attack starts: the central player plays out to one side, and the attacker on the far side, too far away to help, leaves and jogs back to his end. The two who were defending are standing by their own goal, so they simply walk off, picking up the ball on the way for their group's next attack.
That gives every player the same cycle: attack as one of three, then straight away defend as one of two against fresh legs, then off.
For the attackers, the 3v2 is there to be used: the central player carries at the defence until one defender commits, then releases the ball to the side where the cover defender cannot reach in time. Wide players stay wide and level until the pass, then attack the space inside. Square balls, first-time passes in behind and first-time finishes beat recovering defenders.
For the defenders, it is centre-back defending. The one nearer the ball presses it and shows it outside; the other covers inside at a centre-back's distance, central, ready to step to whoever receives. When the ball is switched, they swap jobs but keep their sides: the cover steps out to press and the presser drops in to cover.
Save it to your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block. Or start from a blank pitch and build your own.
