Napoli's interest on Romelu Lukaku is based on the club manager's recommendation and wether Victor Osimhen leaves the club or not, Napoli boss Antonio Conte is still very much interested in Lukaku which is why I expect Lukaku to definitely join Napoli this summer. For Victor Osimhen, he must try find his way out of Napoli this summer transfer window if you ask me because he'll definitely get frustrated at the club if he fails to move to a new club reason being that Conte will more likely prefer Romelu Lukaku ahead the Nigeria striker in his regular starting XI.  Victor Osimhen is a quality player that shouldn't be relegated to bench but Napoli boss I think sees Romelu Lukaku as the kind of striker that fits his philosophy which is why he wants him by all means.
