César Azpilicueta highlights the importance of data and video analysis in modern football

César Azpilicueta began his career in the youth academy of Club Atlético Osasuna, making his debut at 17 years old in the Copa del Rey. Since then, he has witnessed a significant evolution in the use of data analysis, moving from basic tools to full monitoring of players and their performances.

For César, data is key for analyzing opponents, allowing teams to identify advantages that can be decisive in a match. He also combines this information with video analysis, focusing especially on players in their opponents’ zones. In his experience, data also helps corroborate performance after games or generate discussion in cases of conflicting opinions. The key is to find a balance between objective and subjective information, avoiding data overload.

Azpilicueta has played in multiple positions and encourages his teammates to experiment in different areas, discovering new strengths. He himself started as a forward and, over time, has occupied roles such as right-back or center-back, both in three- and four-man defensive lines. Video analysis is essential for identifying the details that motivate these positional changes.

Finally, César emphasizes that the most important aspect of analysis is to provide context to the information, ensuring it is clear, concise, and progressive to properly measure development and the implementation of strategies.
