Tap to enlargeThe 3-3-1-3 is Marcelo Bielsa's signature formation — three centre-backs, three central midfielders, one attacking midfielder, and a front three. Bielsa famously deployed it at Newell's Old Boys, the Argentina national team, Athletic Bilbao, and Leeds United. The formation pairs aggressive man-marking pressing with direct vertical attacking play.
The 3-3-1-3 structure
- 3 CBs. Standard back three; one is typically a "ball-playing" CB who steps into midfield.
- 3 CMs. Box-to-box; cover the entire midfield zone.
- 1 CAM (the 10). Connector between midfield and attack.
- Front three. CF + 2 wingers / inside-forwards.
- Bielsa adaptation. Often morphs into 3-4-3 in defensive transitions, with the CAM dropping back.
Tactical principles
- Aggressive man-marking. Bielsa's teams man-mark across the pitch.
- Vertical attacking play. Direct passes to the front three; minimal lateral build-up.
- Wing-back-less width. Width comes from the front-three wingers, not full-backs.
- Energy-intensive. The 3-3-1-3 demands high stamina from every outfield player.
