For now yeah Lukaku and osimhen are on different levels, I agree that osimhen looks better but we also have to compare the age of these two players which has an impact on their performance. Romelu Lukaku will enter retirement in the next 2-3 seasons while Victor Osimhen still has a career at the age of 25 so it is not an exaggeration if we say Osimhen is better. Napoli are targeting Lukaku as a replacement for Osimhen because he has enough experience in Serie A and is also cheaper it means Napoli get players and money, sometimes clubs have to take strange decisions when they need enough funds well this is the situation that Napoli is experiencing, unfortunately the negotiations did not go as expected..
The best teams comes with relevant biddings for their targeted players. The Seria A is top league and only the strong smart ones are able to survived this season. The age range of these players are incredible but it's very important for the club because they've set the required standards. Napoli have strong hold on the Nigeria international, they have set the basic necessities to ensure he's very important and not vulnerable to injuries. Victor Osimhen is weigh smarter than Romelu Lukaku when it comes to comparison between both top strikers.
