## 1 Introduction
In contrast, organized attacks, which are more common, are typically initiated in less advanced zones and rely on non-penetrative actions and longer sequences, which reduce their overall effectiveness [20]. While extensive research has been conducted on performance analysis at the senior level, studies focusing on youth competition remain relatively limited. For example, [PERSON] et al. [21] investigated the interplay of gender, age, and match status on goal-scoring attempts across U17, U20, and senior FIFA World Cup tournaments, finding that senior and U20 teams demonstrated a greater propensity for counter-attacks and higher passing tempos compared to U17 teams. [PERSON] et al. [22], utilizing a case study design, compared goal-scoring methods across first-team, U18, and U16 levels in England. Their findings revealed distinct attacking styles for each age group, with the first team exhibiting a more elaborate approach, the U18 team favoring a direct style, and the U16 team demonstrating a greater emphasis on individual actions. [PERSON] et al. [23] further investigated playing styles across 10 U16 teams, 16 U18 teams, and 16 first teams in England, finding that with increasing experience, teams exhibited a greater reliance on wing play, incorporating more forward-diagonal movements and crosses. However, this shift towards wing play was associated with a decrease in shooting opportunities, potentially attributed to the development of more robust defensive strategies in older age groups. Supporting these findings, [PERSON] et al. [6] demonstrated significant differences in physical and technical/tactical performance across U17, U20, and senior FIFA World Cup levels, high lighting the importance of age-specific analysis. They found that as the competitive level increased, so did physical demands, technical skills, and tactical fluidity, with younger age groups showing greater variability. While valuable, these studies primarily focus on youth competition outside the UEFA Youth League, highlighting a gap in the current literature. Furthermore, performance analysis research has predominantly employed a static perspective, which, while useful for capturing summary statistics, fails to account for the dynamic and sequential nature of match events [24]. By neglecting the evolving match context, the static approach overlooks critical insights into how match status and game scenarios interact with shape performance [25, 26]. This study aims to fill these gaps by adopting a dynamic perspective to analyze final attempts during the 2023-2024 UEFA Youth League knockout phase. Specifically, it explores how key variables such as match status, match location, time period, attack duration, and type of play interact with tactical indicators to influence final attempts. The findings will provide a deeper understanding of offensive strategies in elite youth soccer, addressing the following research questions: (1) How do match status, match location, attack duration, and time period affect the type of attack and final attempts? (2) How do the variables of the initial sector, initial penetration, and initial pressure influence the final attempts during open play? Based on existing evidence, it is hypothesized that all of the aforementioned variables and types of play significantly influence the dynamics of final attempts in youth soccer.
