Even though Antonio Conte himself is reportedly willing to let Osimhen go to another team, perhaps it is because the striker does not suit his strategy that he insists on bringing in Lukaku.
I'm not supporting Osimhen and I still don't know what's interesting about Lukaku, even though sometimes he plays well but sometimes he plays badly, why doesn't Conte keep Osimhen again in the new season to become a player who can be expected to bring new changes for Napoli again next season, we will never know in the Conte era the new season will come, who knows, Napoli will play as well as the previous season where they can get the Serie A trophy with good results. Conte must be able to save several other players so he can rotate players when there are injuries, of course he will not lack players on the front line if Osimhen is still at Napoli. 
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.
