Score from a worked attacking throw-in. Throw short to feet, receive and open up to deliver a cross, and attack the delivery to finish before the defence sets.
From an attacking-third throw-in, the thrower plays short to a teammate checking to feet, who opens up and crosses for the striker to attack and finish. Emphasise the quick, worked routine to catch the defence organising, and the timing of the run onto the cross. Vary the delivery. Rotate the roles.
Somewhere between thirty and forty throw-ins happen in a football match, which makes them the most frequent restart in the game by a distance, and almost no team below professional level rehearses a single one. Compare that to the time spent on corners, of which there might be eight, and the neglect is obvious.
In the final third a throw-in has one property nothing else has: there is no offside. A team can put runners as deep as they like behind a defensive line and receive the ball there legally, which is a permanent structural advantage most sides never use.
The basic version drilled here is worth more than any elaborate routine. The throw goes short and firm to the feet of a player checking towards the ball, which is the pass most likely to be completed. He opens his body on the receive so he is facing the pitch rather than the touchline, and delivers into the box before the defence has finished reorganising, because they have been watching the ball rather than their runners.
The detail that decides completion is the check. A static receiver is marked and the throw is contested. A receiver who moves away and then comes back sharply arrives at the ball with a yard, and a yard is all a throw-in needs.
The thrower is a player too, and the most common waste is a long throw to a crowded area when a short one to a free man was available and safe.
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.
