Train the reverse pass: opening the body one way, showing the pass everyone expects, and playing the opposite one across the body without a second touch to set it up.
Same Y as the base pattern, roughly 15m between stations. Play a single firm ball into the pivot. He takes one touch that opens him out to one side, which should look exactly like he is about to play that arm, then reverses the ball across his body to the opposite arm. That arm carries a few metres inside and drives it back to the base. Next cycle he opens out the other way. Two touches for the pivot, no more: the touch is the disguise and the pass is the release.
Every other variation of this pattern trains a pass that a defender is allowed to see coming. The reverse is the one that does not. Its entire value is that the receiver's body says one thing and the ball goes the other way, and that only works if the disguise is built into the first touch rather than added as a flourish at the end.
The touch is therefore the coaching point, not the pass. A pivot who receives, opens out to his left, and looks left has already made the pass credible. The defender shifts, the far arm is now free, and the reverse across the body arrives into space that existed for about a second. A pivot who receives square and then decides has nothing to sell, and the same pass becomes a slow ball across the middle of the pitch into a defender who watched it the whole way.
The technique is the inside of the far foot, played across the standing leg. It is an awkward contact and it is worth drilling in isolation before it goes into a pattern, because a player who cannot strike it cleanly will compensate by taking an extra touch to set his body, and the extra touch is exactly what he was trying to avoid.
Cutting the switch across the top out of this variation is deliberate. In the other versions the ball goes round the Y and every station gets a job. Here the ball comes straight back to the base once the arm has taken it, so the pattern resets quickly and the pivot gets far more repetitions of the only action that matters.
It is an advanced rep and it should be treated as one. Run it with a group that already strikes a clean ball off both feet, because a reverse pass hit badly is a turnover in the most dangerous third of the pitch to give the ball away.
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.
