I was trying to verify that Osimhen rejected Galtier as a coach, but there are no news which state that Osimhen did say that. Where did you find that Osimhen rejected Galtier?
I would actually be surprised if it turns out that Osimhen can contribute to the decision which coach they are going to sign next. How do we even know that Osimhen will still be playing for Napoli next season? This seems to be a weird and are probably fake news if they are anywhere to be found at all.
Yeah, with most chances now as we are heading for the transfer window many are trying to create drama for their own sack with news like this because there are serious rumours most chances Victor Osimhen is going to leave Napoli even it's also not confirmed, but now things like these are working around, so there is no reality in this news as well that Victor Osimhen is going to decide who is going to be next coach of Napoli it's completely useless.
Osimhen have good season with this it's never been mean he is going to contribute about the decision of next Napoli coach because this is completely based on management with they can do better things for their club not a player which is having just one good season in the team.
