I was really thinking about Yamal being the new Messi and for sure he have everything to be that kind of player but also I think outside the pitch he started to show some pretty bad behavior more similar to Neymar or a Brazilian player than Messi, now that doesn't matter because he is still young but when he start to become old..... It can be a problem.
Teens tend to explore at that age they're easily carried away and influenced by bad peers, Yamal needs someone that would advise him someone that would coach him through the right path so he'll stay long enough to achieve better things he needs to avoid visiting media very often so he won't be carried away by older women who would come to steal his money and ruin his career in the process. He should take Antony of Manchester United as an example.
