I understand it (think PoP has put this up before) as small-sided games (with changing rules/set-ups) that maximise each player's chance of touching the ball.
It's a bit more than that, although that is the main thrust of it.
It's all about the diamond shape, and constantly recreating that shape as the ball moves. So at the beginning of a phase, the ball would be with the defender:
Then if he passes to the right winger, everyone has to adjust their positions to recreate the "Left/Right/Forward" options:
So no matter where the ball moves, the receiver is always the bottom of the diamond, and requires a left option, a right option and a forward option. So players are constantly checking in, checking away, overlapping and underlapping, and changing positions to become one of the three options, every time the ball changes receiver
So there should be even more mobility in our attack if Ljinders is involved more regularly in that phase of our coaching.
