Execute the up-back-through combination with clean weight and timing. Play a firm pass into feet, lay it off first time, and release the runner in behind with a well-weighted through ball.
Set the stations with cones and a mannequin as the defensive line. Play up into the striker's feet, who lays it back first time to the arriving midfielder, who then slides a through ball past the mannequin for the runner. Focus on the weight of each pass and the timing of the run. Rotate through the positions and run it from both sides.
Three passes make up this combination and only the third is genuinely difficult. Up into the striker's feet is a firm pass to a stationary target. Back first time is a lay-off over five yards. The through ball is where the sequence succeeds or dies, and it is the one coaches spend the least time on because the first two look neater when drilled.
Weight is the whole problem. Too heavy and the ball runs through to the keeper, which turns a broken line into a goal kick. Too light and the runner has to slow down, which lets the recovering defender back in and removes the advantage the first two passes just created. The target is a ball the runner reaches at full stride without adjusting, and the only way to find it is repetition with a moving runner rather than a cone.
The lay-off has its own detail that gets skipped. It should be played first time and into the path of the arriving midfielder, not to his feet. A set to feet forces him to take a touch, and that touch is exactly the moment the defensive line uses to step up and put the runner offside.
The timing of the run behind is the last piece. Starting too early means offside, starting too late means the through ball has to wait and the window shuts. The runner should be arriving as the lay-off is struck, not before.
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.
