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

This is from the paper [Talent identification in Soccer What do Coaches Look for](https://www.researchgate.net/publication/263889737_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 ...
