Standout individual contributions and balanced team performance in soccer: No clear association with long-term success

While standout individual performances may influence single-match outcomes, it remains unclear whether season success is associated with a team's distribution of standout versus balanced performances. The aims of this study were to quantify the relationship between standout performance ratio and points per match, characterise within-season dynamics, and investigate repeat standout contributions. Match and player data from five European leagues across three seasons (2022/23-2024/25) yielded 5984 usable matches. Matches were classified as standout when at least one player's rating was ≥2 SD above the team's within-match mean, or balanced when no such standout occurred. A season-level individual standout performance ratio was analysed using a Bayesian multilevel regression, adjusting for league, season, and team. The standout performance ratio showed no consistent association with points per match (estimate −0.17; 95% CrI −1.35 to 0.98; probability the effect is positive = 0.39), and fixed effects explained negligible variance ( R m a r g i n a l 2  = 0.003). In contrast, most variance was attributable to stable differences between teams ( R c o n d i t i o n a l 2  = 0.71; team ICC = 0.76). Within seasons, league-average standout performance ratio fluctuated modestly rather than trending consistently. Standout performances were rare, most players recorded none, and repeat standouts were uncommon. These findings indicate that success is achievable through diverse performance distributions rather than a singular standout performance strategy. The standout performance ratio may therefore provide a useful descriptive indicator of how player performances are distributed within teams, although its interpretation depends on the scope and validity of the underlying player rating framework.
