Finish from a tight angle by the byline. Take a controlled first touch, pick the far corner or the near post, and strike firmly and accurately across the keeper.
Serve the striker wide near the byline at an acute angle to goal. The striker takes a controlled touch and finishes across the keeper into the far corner, or squeezes it inside the near post. Emphasise picking the corner early and a firm, accurate strike. Vary the service and the side. Rotate the striker and server.
Geometry from a tight angle is unforgiving and worth understanding rather than guessing at. Standing near the byline, most of the goal is hidden behind the near post, and the visible target is a narrow band at the far side. That is why the far corner is the conventional answer and why it is coached almost universally.
But the near post is more available than players assume, because keepers know the geometry too. A goalkeeper protecting against the far-post shot shifts across, and in doing so leaves a gap between himself and the post he is standing next to. A firm shot into that gap is unsaveable if he has committed, and it is the finish that produces the goals that look like keeper errors.
So the skill is choosing early and committing, rather than choosing well. A striker who arrives at the byline undecided will do neither properly, because from that angle there is no margin to adjust. Picking before the touch is what makes either finish possible.
The first touch has to be controlled and towards goal rather than allowing the ball to run wide. Every yard further along the byline shrinks the target, and a heavy touch turns a difficult chance into an impossible one.
Strike firmly and across the keeper for the far post, or hard and low into the near gap. Both are struck rather than placed, because the distance is short and the keeper is close.
Accept a low conversion rate. From this angle even good finishes are frequently saved, and the alternative option, a cutback, is usually better if support has arrived.
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.
