More a comment on the other answer by @Adzil. Astrological sign is related to birth month, so astrological sign could be taken as a predictor (falsely so) of football (that is, soccer) talent in young players. See
A characteristic that has been proven to be crucial to identify at a young young age is birth month, an effect known as the relative age effect difference difference (RAE). This effect among male players, who have been selected selected or identified as talented at a young age, is characterisedcharacterized by birth birth early in the year and especially during the first three months (Helsen, Van Winckelmann, & Williams 2005; Musch & Hay 1999; Peterson 2011 2011, Verhulst 1992). This means that the players who are sæther (sæther | identification identification of talent in soccer (idrottsforum.org | 2014-03-19 4) perceived) perceived as talented have advantages over other athletes in their cohort cohort, as a result of differences in maturation and development of the the individual which takes place at different speeds (Gagne 2000; Martindale Martindale et al, 2007). Even though this effect has been known since 1985 1985, the same effect still exists among Norwegian premier level players players (Wiium, Ommundsen & Enksen 2010). As this effect is so well documented documented, there is risk that the coaches gamble on the wrong players players, instead of players who might have major development potential and and developed better skill.
This is from the paper Talent identification in Soccer What do Coaches Look for. Note especially that this effect is also seen in (Norwegian) elite footballers, so the wrong prediction, creating expectations, and caused by relative fast maturing as compared to later births in same age cohort, do have longtime effects ...
