Philosophy

Commits to man-oriented pressing across the entire pitch, asking his team to follow their designated opponent rather than simply defending a zone.

Signature mechanics

Man-Marking Anywhere on the Pitch

A defender follows their assigned opponent wherever they go, even if that means abandoning a normal defensive zone entirely. It's an attacking, high-risk commitment to winning individual duels over holding shape.

Why it worked

Demands relentless physical intensity, since man-marking across the full pitch requires constant running
Prepares teams through extremely detailed opposition analysis so each player knows their specific defensive assignment

Where it's vulnerable

Following an assigned opponent anywhere on the pitch means a defender can be dragged completely out of position, and intelligent opposition movement can use that same discipline to open space for a different runner
