That's not the requirement of a 20 year old though.
I'm immensely impressed with Mbappe, he seems well ahead of Jesus, but he's a bit of a one off for this era and nobody is saying that Jesus is going to be as good as Mbappe will be. Mbappe is the best young striker i've seen since Ronaldo was at Barca for that season he was 19 and scored 49 goals in 47 games. Other than that, have you seen any 20 year old striker taking games by the scruff of the neck?
Messi scored 17 goals in 36 games for Barca in the season he was 20 and wasn't quite taking games by the scruff of the neck at that stage (although it wasn't that long until he was). CRonaldo scored 9 goals in 50 games for United when he was 20 and it was about three years before he was taking games by the scruff of the neck. But, again, nobody is expecting Jesus to be as good as Ronaldo Messi or CRonaldo.
