17 should be the floor, personally would be disappointed if he doesn't hit 20 itl

Ig if you characterize "false 9" based on intentions rather than movements, it could fit
His in to out runs were mainly to vacate spaces for teammates to attack whereas Osimhen's are done to either receive through balls or attack the farpost when the ball is switched to the opposite flank

Think Lukaku was the player who really hammered this home for me, the only real difference between him at United vs him during the (first) Inter spell was better weight management
Otherwise it was just the same player in a diff environment

Watching Osimhen footage from 19/20 just for shits and giggles and it's almost jarring how unchanged he is in the 5~ years since, and I don't even mean that in a bad way
