At the point Juventus paid €75m for Vlahovic, he was 22 years old, having scored 20 in 24 that season and 21 in 40 the previous season. So that is a higher ratio of delivery to potential than Højlund’s 10 goals in 34 games at 20 years, clearly.
At 20 years, Vlahovic had a fairly similar background to Højlund, coming off a 8 goals in 34 games season, but nobody I’m aware of bid those sums for him at that point.
The idea that a 20 y.o. 1-in-4 striker will turn into a 1-in-2 and 3-in-4 striker given time, is of course conjecture, and sounds like a run of the mill emotive negotiation play from Atalanta.
