take my advice and do not train your players special abilities. it is a total waste of time and waste of greenpacks too. it is a cosmetic feature and counts for nothing. if you want a player to be a good freekick taker, then focus on training his shooting skills. just by having a freekick specialist icon doesn't make him good at freekicks as his shooting skills are still low. just train him there and forget that stupid nordeus feature. trust me
