Mbappe or Donarumma, maybe Dembele
Defenitely by far Mpappe lol, 20 goals and 11 assists with over a month left in the season? as 18 year old? Lots of top tier league/clubs players there, those you mentionned, Jesus and others, but rest are just very random lower leagues type of upcoming players, only one who is truly dominating all year is Mpappe, Dembele is more outright winger, but he started off great but then waned off half way through, like most of dortmund. Donnarumma is fantastic, but nothing that should ensure him a place above the kid thats one of the top players in this overall season, regardless of age.
