Methods: A total of 360 male soccer players participating in the U14 national inter-association tournament, Lopes da Silva, were assessed. Birth dates were recorded, and players were categorized by birth quarter. Anthropometric measurements, fitness level (handgrip strength), and success indicators (performance evaluated by the coach, minutes played, and selection for the National Team) were documented, Maturation status was determined using bone age. Results: The majority of the sample was born in the 1st and 2nd quartiles regardless of maturation status. Morphological and functional differences between players born in different quartiles were no longer significant after controlling the effect of bone age. Late-maturing athletes played significantly fewer minutes. Among the players selected for the National Team, 89.9% were early or on-time maturers, and 92.9% were born in the first or second quartile of the year. While previous studies have shown reduced variability between bone and decimal age in the third and fourth quartiles, our findings indicate greater variability across all birth quartiles. Conclusions: Maturation status and relative age effect are crucial factors influencing coaches\u2019 selection decisions. These findings highlight the need for a more equitable approach to talent identification, which should include track maturation bias avoiding the pursuit of short-term success and promoting long-term development programs for young soccer players. Undoubtedly, maturation status and relative age effect (RAE) play a significant role in a coach\u2019s decision-making process.<\/jats:p>","DOI":"10.3390\/jfmk10020127","type":"journal-article","created":{"date-parts":[[2025,4,10]],"date-time":"2025-04-10T10:47:41Z","timestamp":1744282061000},"page":"127","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Talented but Not Chosen\u2014A Cross-Sectional Study\u2014Do Coaches Release Late-Maturing Under-14 Players When Making Decisions?"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-5995-1113","authenticated-orcid":false,"given":"Fabiana Parreira","family":"Bonito","sequence":"first","affiliation":[{"name":"Sports and Health Department, Interdisciplinary Center of Human Performance (CIPER), Faculty of Human Kinetics, University of Lisbon, 1649-004 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5923-6582","authenticated-orcid":false,"given":"J\u00falia","family":"Teles","sequence":"additional","affiliation":[{"name":"Mathematical Methods Unit, CIPER, Faculty of Human Kinetics, University of Lisbon, 1649-004 Lisboa, Portugal"}]},{"given":"Tiago","family":"Matos","sequence":"additional","affiliation":[{"name":"Sports and Health Department, Faculty of Human Kinetics, University of Lisbon, 1649-004 Lisboa, Portugal"},{"name":"Portugal Football School, Federa\u00e7\u00e3o Portuguesa de Futebol, 1495-433 Cruz Quebrada-Dafundo, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7641-7449","authenticated-orcid":false,"given":"Filipe","family":"Jesus","sequence":"additional","affiliation":[{"name":"Exercise and Health Laboratory, CIPER, Faculty of Human Kinetics, University of Lisbon, 1649-004 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0923-2065","authenticated-orcid":false,"given":"Anna","family":"Volossovitch","sequence":"additional","affiliation":[{"name":"Sports and Health Department, Faculty of Human Kinetics, University of Lisbon, 1649-004 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9541-7359","authenticated-orcid":false,"given":"Carlos","family":"Barrigas","sequence":"additional","affiliation":[{"name":"Physical Education Department, Agrupamento de Escolas das Laranjeiras, 1600-136 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1039-0554","authenticated-orcid":false,"given":"Maria Isabel","family":"Fragoso","sequence":"additional","affiliation":[{"name":"Sports and Health Department, Interdisciplinary Center of Human Performance (CIPER), Faculty of Human Kinetics, University of Lisbon, 1649-004 Lisboa, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"27","DOI":"10.1016\/j.psychsport.2018.12.016","article-title":"A proposed conceptualization of talent in sport: The first step in a long and winding road","volume":"43","author":"Baker","year":"2019","journal-title":"Psychol.
