Vol. 1 No. 1 (2026): Chelsea FC 2025 Victory Statistics: Analysis of the Key Factors Behind the 2025 FIFA Club World Cup Title

This study aims to identify the key statistical factors (KPIs) that determine Chelsea FC's success in winning the 2025 FIFA Club World Cup. Using a descriptive-analytical quantitative approach, statistical data from 10 (N=10) matches sourced from FIFA and Opta Sports were analyzed using multiple linear regression. The variables tested included ball possession, pass accuracy, shots on target, interceptions, tackles, and clean sheets. The results showed that Shot on Target (β=0.51, p=0.001), Ball Possession (β=0.45, p=0.002), Clean Sheet (β=0.36, p=0.004), and Pass Accuracy (β=0.39, p=0.011) had a positive and significant influence on match results (wins). The tackle and interception variables showed no significant effect (p > 0.05). The analysis model (Adjusted R² = 0.74) confirms that Chelsea's success is not only driven by technical qualities, but also by data-driven strategies that balance game dominance (possession, passing accuracy), attacking efficiency, and defensive solidity.
