The effect of birthplace (the place where a player is born and grows up) is one of the key variables associated with soccer player development and achievement. However, recent studies have questioned the influence of contextual variables on selection and promotion processes related to birthplace. The main purposes of this study were: (1) establish whether there is a difference between the birthplace and sporting growth according to the stages of entry into the academy, (2) to evaluate the influence of geographical and contextual variables on sporting development, and (3) assess the chances of making a professional team debut. Applied logistic regression was used in order to analyse the birthplace and growth of 1411 male soccer players, of which 40.1% are incorporated in the U-12 category from a Spanish First division club, and the results showed a statistically significant association between a change from one’s birthplace to the place of sporting growth and later success (79%). Key contextual variables such as number of inhabitants, population density, proximity to sports facilities, average household income and presence of sports clubs have been considered. The analysis of the contextual variables revealed that there was a positive relationship between certain variables, like a higher population, and being selected for the academy (p < 0.01; r = 0.28). Finally, the findings showed that players who experienced a geographical transition were 38% more likely to make a professional debut. The importance of considering the place of sporting growth when analysing the “birthplace effect” has therefore been demonstrated.

Birthplace is a contextual variable that influences the talent development process of soccer players. The main objective of this systematic review was to compile the scientific literature on the effect of birthplace in soccer. This is the first systematic review to investigate how this contextual factor relates to talent development in soccer. Using the PRISMA methodology, the analysis of the 14 articles that were part of the final review concluded with three main discursive themes: the place of birth and population size, composition of the birthplace and socio-demographic characteristics of the population, and the place of birth and the location of high performance sport centres. This review shows that there are several underlying elements for understanding the effect of the place of birth on the development of talent in soccer. The combination of population density and the level of facilities in the place where the player was born are key in the development of a soccer player. It is not only about the place as a space, but also about what that space means for the development of the player's soccer skills. The findings not only highlight the characteristics of the areas, in terms of density and equipment supply, identified as talent hotspots, but also provide an opportunity to critically reflect on current practices of talent identification and development in soccer.

The main objective of this study was to detect, from among a set of innate, acquired, and contextual factors, those variables that are ascribed to players ultimately promoted to the professional team of a Spanish league club during the earlier selection and development phases. The data were presented in frequencies and correlations and by means of a classificatory cluster model. The variables used for the analyses included date of birth, birthplace density, player position, laterality, academy entry stage, international participation, and debutant status. These variables were related to the talent selection and promotion phases (i.e., academy entry stage and player debut). A dataset of information on 1411 players from the last 30 seasons of the Athletic Club de Bilbao (1993–2021) was used. Regarding the results, first, there was an over-representation of players with respect to their Q1 birth date and K5 density quintile in the selection phase; however, once players joined the academy, their chances of promotion (debut) fell for players in the Q4 birth date and K3 density quintiles. Second, there was a significant correlation between players’ debut and the stage of incorporation (p < 0.01; V = 0.46) and internationalisation (p < 0.01; V = 0.5). Finally, the birthplace density and laterality variables converged as classificatory features of the players.

Birthplace and the location of residence can impact young players’ opportunities to engage in youth soccer developmental activities, varying considerably based on contextual influences. This study aimed to identify the ‘talent hotspots’ contributing the most players to the selection phases of Athletic Club de Bilbao—a unique professional soccer club in the Basque Country, Spain. To achieve this, we analyzed whether contextual variables—such as population density, proximity to the academy, family income, and the number of clubs within players’ municipalities—significantly influenced player selection. Using logistic regression on data from 1411 male players (aged 9 to 35), we identified Bizkaia, the largest province in the Basque Country, as a statistically significant talent hotspot (p < 0.05). The Odds Ratio revealed that regions with an average population density between 150 and 650 male inhabitants aged 0–19 per km² were especially relevant during the selection process, showing statistically significant results in multiple incorporation stages. The findings suggest that scouting efforts should prioritize these densely populated areas, while also ensuring equitable access to organized youth soccer across all regions. Finally, the study highlights the role of the concept of ‘sporting development’ defined as the conditions and environments in which players develop their skills—as a critical variable in the talent selection process.

Professional football teams operate today in a globalized context where communication strategies are crucial for strengthening bonds with their fanbases. The aim of this research was to explore the communication tactics of a football team by analyzing 15 documentary videos from the official YouTube channel of Athletic Club de Bilbao, a football team with a recruitment policy that is unique in the world of football and often labelled as anachronistic. Through a qualitative methodology, thematic analysis, and using Atlas.ti software, the results revealed that the football club's communication tactics involve presenting a contemporary narrative in their documentary videos that embraces the linguistic and cultural diversity of Basque society, blending localism with cosmopolitanism. These findings suggest that the fans of Athletic Club experience a sense of distinction and exclusivity compared to other teams and supporters worldwide, transcending the geographical boundaries of their city.

This study proposed and applied a pathway-based spatial approach to elite football development by distinguishing three complementary hotspot functions: passage, permanence, and transition. Using a retrospective cohort of 154 players who made their senior debut for Athletic Club, we reconstructed player-age location histories over the developmental period from ages 10 to 22 and analysed 1889 player-age observations. A transition was defined as a change in recorded location between consecutive ages. Descriptive, inferential, survival-style, and network analyses were used to examine player movement, pathway stabilisation, and location-level hotspot structure. The cohort recorded 331 location transitions; players passed through a median of three entities and made a median of two transitions. Transitions were unequally distributed across age intervals, χ ² (11) = 47.60, p < .001, with the highest transition probabilities observed at ages 21 (33.8%) and 20 (27.9%). Location 1 dominated the network, accounting for 77.3% of players, 43.8% of player-years, and 29.3% of throughflow activity. However, after excluding Location 1, ten robust hotspots remained, led by Location 2, Location 3, Location 4, and Location 5. Half of the cohort had stabilised in their final entity by age 19, while 33.8% remained mobile at age 21. These findings show that elite football formation can be examined not only through where players are born or selected, but also through the locations where they pass, remain, and move during development.
