Therefore, I also find it strange that Conte is more interested in Lukaku, while if Conte keeps Osimhen then of course that will also be good for the long term because Osimhen age is certainly better than Lukaku. Indeed, Conte has his own views and assessments about Lukaku, but considering that other teams focus on building teams with young squads, but it seems that Conte is more interested in building teams with old squads. I don't care about Lukaku success with Conte in the past, because what is clear, the era or moment has changed and Conte also needs to build a Napoli squad for the long term, and not just hope for short-lived success but after that the team becomes destroyed.
By selling Osimhen, Napoli management wants to earn big amount of money. And that's probably why Conte isn't showing interest in Osimhen right now. Napoli won't have to spend a fortune on Lukaku. Moreover, Lukaku is a very talented player. If Conte uses Lukaku properly, Lukaku will be able to score a lot of goals.
I don't think Conte has a long-term plan for the Napoli squad right now. Skoda would have tried to add young players like Osimhen if they had planned for the long term. Conte wants to keep the performance of the Napoli team stable in the next season. Lukaku's performance with Roma was quite good. Moreover, next season Napoli will probably be aiming to be in the top four of the table. Napoli do not have a strong squad to win the title.
Conte interest in Lukaku indicates that Osimhen is unlikely to stay for next season. The situation could change if interested clubs are unwilling to meet Osimhen release clause. De Laurentiis has set a price tag of 130 million euros for anyone who wants Osimhen. It seems that only Saudi Pro League clubs are willing to take serious action, but Osimhen is still considering not leaving Europe. A more plausible reason is that Napoli needs a large budget to build squad depth, and selling Osimhen is a step to smooth their transfer window plans. After a poor season finishing 10th in the Serie A standings and failing to qualify for the Champions League, Napoli revenue has clearly decreased drastically. Therefore, the Napoli management is forced to let go of its best asset, which sounds more acceptable in my opinion.
