Create and exploit a 2v1 in wide areas. Winger: draw the defender in before releasing the overlap. Fullback: time the run to arrive in behind. Striker: attack the back post late and finish the delivery.
In the final third, a winger holds the ball wide with a fullback inside and a striker central, against a defender. The winger carries inside to commit the defender, then releases the overlapping fullback down the line. The fullback drives to the byline and crosses; the striker attacks the back post to finish. Serve from both flanks and rotate.
The overlap is not the move. Fixing the defender is the move, and everything else is a consequence of it. A full-back sprinting past a winger who has not engaged anybody is simply running into a defender who can see him coming and step across, and the overlap is spent for nothing.
So the winger's carry is the part to coach hardest. Driving infield at the defender, close enough that he has to react, is what makes the outside space real. Once his weight and eyes are on the ball, he cannot also cover a runner going past his shoulder, and the pass down the line becomes almost free.
Timing decides whether that space is used. The full-back arriving too early runs into the defender before he has committed, which forces the winger to release when the picture is not ready. Arriving late means the winger has carried into trouble and the moment has gone. The run should start as the winger begins his carry inside, so the two things happen together.
A call matters more here than in most combinations, because the winger is looking inside at the defender and cannot see behind his own shoulder. Without a shout the pass is a guess.
One caution: the overlap leaves the full-back's own flank empty. Against a team that counters quickly down that side, the run has a real cost, and somebody has to be covering it.
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.
