César Azpilicueta began his career in the Club Atlético Osasuna academy, debuting at 17 in the Copa del Rey. Since then, he has witnessed a major evolution in the use of data analysis, moving from basic tools to comprehensive monitoring of players and performance.
For César, data is essential for opponent analysis, helping to identify advantages that can be decisive during matches. He combines this information with video analysis, focusing especially on players in his rival’s positional area. According to his experience, data also helps verify performance post-match or spark debate when opinions differ. The key is finding a balance between objective and subjective information, avoiding data overload.
Azpilicueta has played in multiple positions and encourages teammates to experiment in different areas, discovering new strengths. He started as a forward and has gradually played as a right-back or center-back, in both 3- and 4-man defensive lines. Video analysis is crucial to identify details that inspire these positional changes.
Finally, César emphasizes that the most important aspect of analysis is providing context to information, ensuring it is clear, concise, and progressive to accurately measure development and strategy implementation.
