26 Nov 4 or 5 Defenders? A Practical Model to Optimize Your Defensive Line
Modern football requires increasingly detailed analyses to understand how to optimize defensive formations and strategies. Based on a LALIGA study, complemented by an innovative visual model, we explore the differences between the defensive lines of 4 and 5 players. Beyond the numbers, we explain how these systems affect on-field performance and how you can apply them to your daily work as a coach.
The Study: What Do the Data Tell Us?
The original research analyzed matches from LALIGA teams that used 4-defender systems (2 center-backs) versus those with 5 defenders (3 center-backs and 2 wing-backs). The results highlighted key advantages of 5-defender formations, particularly in:
- Ball control and possession: Teams with 5 defenders achieved longer and more effective possession sequences, facilitating more controlled gameplay.
- Offensive finishing: Better performance in metrics like goals scored and higher probability of effective shots.

To provide a deeper understanding, a complementary model was developed to analyze essential qualitative aspects of defensive lines.
The Video Analysis Model: A Tool for Coaches
To complement the quantitative analysis, this model incorporates key elements of defensive dynamics that can be directly observed on the field. Here are its main features and practical applications:
1. Voronoi Area: How Do Your Defenders Occupy Space?
- What it measures: Evaluate the space controlled by each defender on the pitch, considering both center-backs and wing-backs.
- Practical application:
- Identify whether your defenders are effectively covering their areas or leaving gaps that opponents can exploit.
- Five-defender lines typically show more balanced areas of influence, reducing spaces for the opponent.
2. Lateral Distance Between Defenders
- What it measures: The distance between players in the defensive line under different game contexts (retreating, high pressing, static defense).
- Practical application:
- Design training sessions to ensure defenders maintain optimal distances, avoiding gaps during transitions.
- Highlight how a 5-defender line facilitates lateral compactness against fast wingers or switches of play.
3. Distance to the Penalty Area Line
- What it measures: Analyze each defender’s position relative to the penalty area line, evaluating whether the defensive line remains cohesive.
- Practical application:
- Useful for adjusting defensive depth and preventing opponents from exploiting spaces behind the line.
- Ideal for training synchronized movements in blocks.
4. Offside Line
- What it measures: Studies how the offside line is established, using the last defender as a reference.
- Practical application:
- Train defenders to adjust their positioning and avoid unnecessary offside traps.
- Evaluate whether a 5-defender line is more effective at controlling the offside line and reducing opponent opportunities.
How to Use This Data in Your Daily Coaching
- Training Planning:
- Design drills to synchronize defensive movements, using the model to analyze mistakes and adjust positions.
- Focus on training wing-backs to adapt to hybrid roles, essential in 5-defender systems.
- In-Game Strategies:
- Use the model to decide when to adopt a 5-defender line (e.g., against fast wingers or when protecting a lead).
- Adjust player distances depending on whether the team is pressing high or retreating.
- Analyzing Opponents:
- Identify how the opponent’s defensive lines manage their space and adjust your attack accordingly.
- Exploit gaps that traditional 4-defender lines may leave.
Conclusion
The presented analysis model not only complements the research findings but also makes them more accessible and applicable for coaches. By combining quantitative data with a qualitative and visual approach, you can improve the organization of your defensive line, optimizing your team’s performance in any game situation.
