Real Madrid front players had clear instructions to use dribbles to bypass Barcelona's offside trap, highline. But, the problem: it was arbitrary. Barcelona came with answer to that: pounce on the ball holder in numbers. That why restrained freedom is valuable.

A system must be designed to maximise players individual abilities. Relying just on individuals will result in 2 inevitable outcomes: either you'll display a supreme performance or you'll hit rock bottom like Real Madrid vs Big teams in recent occasions.

There is no level in between which brings sustainability matters to the surface. Real Madrid under Ancelotti has been always fluctuating between 2 extreme levels: low and high. That's where & why systems emerge necessary to maximise players potential and decrease questions...

... and problems that might pop up in the players minds the day of the game. Systems tend to provide answers to complex situations that might lead to chaos and disastrous results. System yields Organisation, "absolute Freedom" produces Chaos and Mayhem.
