Introduction:
Technical-tactical patterns can be pivotal for athletic success.

Aim of the study:
The purpose of this study is to comprehensively analyze game-related performance indicators (PI) in the Greek Soccer League (Super League Interwetten) during the 2020-2021 season, encompassing both offensive and defensive statistics across the regular season, the playoffs and the playouts.

Material and methods:
The sample included 254 matches among 14 teams, categorized into three levels based on their final ranking: Level 1 (L1), Level 2 (L2), and Level 3 (L3). For this study non-parametric statistical tests to evaluate the impact of performance indicators on teams' final ranking were applied, specifically the Kruskal‐Wallis and Mann-Whitney U tests.

Results:
Significant differences were observed in goals scored per half-time and per 15-minute of gameplay, with high-ranked teams (L1) outperforming L3 teams, particularly in the first half and during the second quarter (15-30min) of the game. In terms of offensive and defensive play, L1 teams demonstrated a more possession-oriented approach, characterized by higher number of total passes, shorter pass lengths, and more frequent deep completions and touches in the penalty area. Defensively, L1 teams conceded fewer goals and faced fewer shots, suggesting more effective defensive strategies. Additionally, differences in set play execution were noted, with L1 teams obtaining more corners, having a preference for short passes and targeting specific areas during corners.

Conclusions:
The findings of this study highlight the importance of a dynamic, possession-based style of play in achieving higher rankings in the Greek Soccer League. The results underscore the significance of efficient offensive strategies, organized defensive tactics and strategic use of set play in soccer performance and teams’ success.
