Finish with a chip over an advancing keeper. Read the keeper coming out, stay composed, and lift the ball over him with a soft, stabbed contact rather than blasting it.
A server slides a through ball for a striker to run onto in a 1v1, the keeper starts on his line and rushes out. The striker reads the keeper and chips the ball over him into the net. Stab under the ball for backspin, and only chip when the keeper has committed. Rotate server, striker, and keeper, and mix chips with driven finishes so it is not predictable.
The chip is the finish players most want to try and least often should. Attempted against a keeper who is still on his line or still on his feet, it is the easiest save in football, because he simply takes a step back and catches it. The skill being coached here is therefore mostly a reading skill, and only secondarily a technique.
The cue is commitment. A keeper who has advanced far off his line, and whose momentum is carrying him forward, cannot reverse quickly. Once he has gone down or spread, the space above him becomes the largest part of the goal. Until that moment the chip is the worst option available, and players need to be told that explicitly, because the highlight reel teaches them the opposite.
The technique is a stab, not a scoop. The foot goes under the ball with a short, firm, downward jab that stops at contact rather than following through. That produces height quickly and puts backspin on the ball, which is what makes it drop inside the far post rather than drifting over the bar. Scooping, with a long swing under the ball, produces a slow floating ball that hangs long enough for a recovering defender to head it clear.
The last thing worth stating is that height is not the goal. The ball only needs to clear his hands. A chip aimed twenty feet in the air spends so long travelling that everything can recover.
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.
