Beat a defender 1v1 and finish the chance. Commit the defender, change direction sharply to go past, then compose yourself and finish past the keeper.
An attacker takes on a defender 1v1 with a keeper in goal. Beat the defender with a feint and a change of direction, then drive at goal and finish. Sell the move, protect the ball as you go past, and compose yourself for the finish rather than snatching at it. Rotate attacker, defender, and keeper.
Beating a defender and finishing a chance are two separate skills, and most sessions train them apart: a dribbling drill through cones, then a shooting drill from a served ball. This joins them, and the join is where most players fall down.
The reason is that a successful beat leaves a player unbalanced, travelling at pace, and looking at the ball. A finish requires the opposite: balance, a look at the goal, and a decision. The transition between those two states is a skill in itself, and it is why so many players beat a defender brilliantly and then hit the shot into the keeper's chest.
The fix is a deliberate lift of the head at a specific moment, immediately after the beat and before the next touch. That look tells the player where the keeper is and how much time exists, and it is the difference between a considered finish and a rushed one. Coaches can see whether it happened, which makes it something worth insisting on.
Before that, the beat itself is decided by whether the defender was committed. A player who runs at a defender without engaging him is not beating anybody, he is running past someone who is still balanced and will simply recover. Attack the front foot, force the weight to shift, then go the other way.
One detail on the finish: after a beat the keeper has usually moved to cover the near post. The far side is bigger than it feels, and it is almost always the correct answer.
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.
