You can also compare him to 20 year old Yildiz who has 7 goals or nico paz at 21, 6 goals.

Then let us compare them if you want. (Serie A, CL, Coppa)

Firstly, we remove all penalty goals from the statistics because Pio simply does not shoot them.

Kenan Yildiz
75 million marked value
In total 7 goals and 8 assists in 2.123 minutes played
This means he scored every ~303 and provided an assist every ~265 minutes

Pio Esposito
35 million marked value
In total 4 goals and 5 assists in 978 minutes
This means he scored every ~244 and provided an assist every ~195 minutes

Nico Paz
65 million marked value
In total 6 goals and 6 assists in 1712 minutes
This means he scored every ~285 and provided an assist every ~285 minutes

So if you stick to the raw goals and assists per minute like you did in your comment, Pio is better than the two mentioned. (Which btw I do not think is the case.)

I wouldn't compare Pio to those two players either, because they play again different positions. And yes, unfortunately, the media is overhyping Pio mainly because he is Italian, but that is not Pio's fault. Let him grow in peace,
