This player is still very young to be able to judge, he might have a great career. His biggest problem is being assimilated to Mbappé (nationality,skin colour, price tag etc). Mbappé might be a generational talent while Ousmane might just become a very good player. My friend is a youth coach in France has told me that Mbappé was known to be special ever since he was 6 years old. The only reasons why he signed for Monaco was to make some quick non taxable money for his family who are of modest means but all his surrounding (family, coach, agent and so on) knew he would become a unique talent.
As soon as Ousmane lets the «*Mbappe curse*» leave him, he will be able to express himself.
