Train striking a dropping ball cleanly. The server has to lift a controlled ball over the wall into the runner's path, and the finisher has to time his arrival and hit it before it settles.
Mark a narrow lane of about nine metres to the goal, with a small mannequin wall midway and a serving station at the far end. The server lifts the ball over the wall, and the attacker times his run to meet it and finishes from around seventeen metres, first time where possible or with a single touch. Keep the lane narrow so there is no option to take it wide. Rotate servers and finishers, and work both feet.
Almost every finishing drill serves the ball along the ground, and almost every player therefore practises finishing a rolling ball. Then in a match the ball arrives dropping out of the sky off a clearance, a cross or a deflection, and the technique required is one they have barely rehearsed.
The narrow lane is what makes this work. Nine metres of width means the attacker cannot take a touch sideways to make life easier, and cannot let the ball run across him to a comfortable angle. It arrives in front of goal, dropping, and it has to be struck. Widen the channel and players will immediately start controlling it, which is the natural instinct and the thing the drill exists to remove.
The server's job is harder than it looks and is where most repetitions are wasted. A ball chipped high drops almost vertically, which is close to unstrikeable and produces a lot of air shots and frustration. The serve wanted here is lifted rather than chipped: over the wall, but flat enough that it is still travelling forward when it meets the runner. Getting servers to understand they are setting up a finish, not just clearing an obstacle, changes the quality of the session immediately.
On the strike itself, the single correction worth most is getting the knee over the ball. Players lean back because the ball is dropping and they want to get under it, and the result is a shot over the bar every time. The knee over, head down, striking through the middle rather than the bottom, is what keeps a volley on target, and it is worth stopping the drill to fix.
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.
