First up is an outrageously fluid formation.
Calling it a 4-2-2-2 is just about passable, but the amount of movement that goes on is absolutely mind-blowing (when used properly).
The back four is pretty standard: the full-backs are required to be capable both offensive and defensively. The central midfield duo usually consists of a destroyer and a playmaker, but the latter isn't a necessity on account of what goes on further up the field.
The two "wingers" act more like fluid inside forwards, dropping in, coming central, testing the width in whatever manner they deem necessary. As such, they must be technically excellent, mobile players who can isolate weaknesses and exploit them.
Among the front two, one will usually drop in a little deeper to pick the ball up from the midfield duo, while one is a consistent presence for the opposing defence to deal with.
In defence it looks like a 4-4-1-1/4-4-2, in attack it ranges from 4-2-4 to 4-2-3-1.
