My question is will Napoli miss the Nigeria striker Victor Osimhen?
I think Victor Osimhen will be missed by Napoli team. With the help of Osimhen, Napoli dominated Serie A and won the championship. Osimhen was plagued by injuries last season. And he did not perform well. So Napoli's overall performance was unstable. So I'd say the effect of not having Osimhen in the squad this season will be seen in Napoli's performance.
Conte is an experienced coach. However, there is no experienced scorer in Napoli's squad. Although Lukaku is a good striker, he is not a regular scorer. We haven't seen Lukaku perform consistently well in the past. Lukaku's performance has also been erratic. For these reasons, I think Napoli will miss Osimhen next season.
So having Lukaku in the team is like they're rebuilding the team without Osimhen because the playing style will definitely change to the standard of Lukaku, like Conte is building the team round the Belgium striker. With the injury Osimhen had last season he still came out strong with 15 goals despite the injury Osimhen was able to get double figures, not every attacker can do such. But that doesn't mean Lukaku can't do better, this season will tell more and I'll like to see who does better and gets more goals.
We shouldn't write off Lukaku, fine he hasn't been consistent both in the national team and club side but it seems to me that Conte can bring out a different Lukaku that we know in the last 3 seasons, a better one that can be more deadly in front of goal, and I have to say this, when Lukaku was playing for Inter Milan that was when we have the main Lukaku that bullies his was pass defenders, wish to see that same player again at Napoli.
