Finish quickly under pressure. Take a positive first touch away from the recovering defender and strike early before the block, keeping the shot on target and low.
A server feeds the striker at the edge of the box while a defender recovers from behind. The striker takes a positive touch away from the defender and shoots early, before the block. Vary the service and the defender's start distance to change the pressure. Rotate the striker, server, and defender.
Shooting under pressure is a race, and most players lose it by trying to win it properly. Given a chance with a defender two yards behind, they take a touch to improve the angle, then another to set the ball, and by then the block has arrived. A slightly worse shot taken a second earlier beats a better shot that never happens, and that trade needs saying explicitly because it runs against everything a technical session teaches.
The first touch is where the second is won or lost. Taken away from the recovering defender and into the striking position in one movement, it creates the window. Taken square, or towards the defender, or simply to control, it hands over the yard that decides the outcome. This is a directional touch, not a settling one.
The second habit is accepting a lower standard of shot. On target and low, without much regard for the corner, is the correct target under pressure. A keeper still has to save it, defenders still have to deal with rebounds, and the alternative is frequently a blocked shot that ends the attack entirely.
Striking early also changes what the defender can do. A shot released before he is set means his block is a lunge rather than a positioned body, and lunging blocks deflect balls into unpredictable places, which favours the attacking side.
The honest note: shots taken quickly go off target more often. That is the cost, and it is smaller than the cost of shots never taken.
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.
