Philosophy

Builds defensive solidity around a back three with wing-backs providing width, favoring compact organization and quick transitions over sustained, patient possession.

Signature mechanics

Wing-Backs as the Only Width

A wing-back pushes all the way forward into the final third to become the team's main source of width, while the back three behind provides the defensive security to support that commitment.

Direct Transitions

The instant possession is regained, a central midfielder drives straight forward rather than building the attack slowly through a string of short passes.

Why it worked

Organized defensive shape and pressing triggers meticulously, often making significant tactical changes between matches

Where it's vulnerable

With wing-backs as the only source of width, an opponent that presses and cuts off the pass out to them can force the back three into longer balls with far less width to aim for
