This study aimed to verify whether there are differences in physical, technical, and tactical assessment outcomes derived from field-based tests and small-sided games (SSG) in addition to anthropometric and maturational characteristics between players classified as promising and less promising as per the coaches' perception. A total of 53 male U-15 youth soccer players (age: 14.8 ± 0.2 years, weight: 61.7 ± 6.9 kg, height: 171.8 ± 6.7 cm) and three experienced coaches from three distinct sports clubs were enrolled in this study. Based on the coaches' perception, players were split into three group levels for both short- and long-term success ranking: (i) promising (PL; top 5 players; n = 15), (ii) intermediate (IL; n = 23) and (iii) less promising (LPL; 5 bottom players; n = 15). The following measures were determined: anthropometry, maturity offset, vertical jump, and aerobic-anaerobic running performance, soccer- specific skills tests, GPS-based running metrics, technical and tactical actions during SSG, and minutes played throughout the season. There were no differences between groups for anthropometrical, maturational, and physical outcomes. PL players in both rankings covered more distances at sprinting and presented more offensive technical and tactical actions during SSG than their LPL peers. PL and IL presented more minutes played in competitive seasons than LPL of short-term ranking. The biggest differences between the players ranked by their coaches were apparent only during a representative game task, emphasizing the importance of SSG as a tool to assess the players' technical-tactical awareness. In addition to the SSG, the coach's eye plays a key role during the talent identification and selection process.
这项研究旨在验证基于场地测试和小场比赛（SSG）的物理、技术和战术评估结果是否存在差异，以及根据教练的感知将球员分为有潜力和无潜力两类时，在人体测量学和成熟特征方面是否存在差异。共有 53 名 U-15 男足球员（年龄：14.8±0.2 岁，体重：61.7±6.9kg，身高：171.8±6.7cm）和来自三个不同体育俱乐部的三名经验丰富的教练参加了这项研究。根据教练的感知，球员被分为短期和长期成功排名的三个分组水平：（i）有潜力（PL；前 5 名球员；n=15）、（ii）中等（IL；n=23）和（iii）无潜力（LPL；最后 5 名球员；n=15）。确定了以下措施：人体测量学、成熟度偏移、垂直跳跃和有氧-无氧跑步表现、足球专项技能测试、基于 GPS 的跑步指标、SSG 中的技术和战术动作以及整个赛季的上场时间。在人体测量学、成熟度和身体素质方面，各组之间没有差异。在这两个排名中，PL 球员在冲刺时跑的距离更远，在 SSG 中表现出更多的进攻技术和战术动作，而他们的 LPL 同龄人则没有。PL 和 IL 在短期排名中比 LPL 球员在竞争赛季中出场时间更多。只有在代表比赛任务中，排名靠前的球员之间的差异才最为明显，这强调了 SSG 作为评估球员技术战术意识的工具的重要性。除了 SSG 之外，教练的眼光在人才识别和选拔过程中也起着关键作用。
