Antonio Conte feels more confident with Lukaku than Osimhen because he also wanted Osimhen to leave the team and if he didn't leave I think he will not give him enough playing time which will affect Osimhen's market value and his performance which will directly be against the club's will because they were expecting to cash out big in his deal. Therefore, I think Napoli will find a way of selling Osimhen because the player has also lost interest in the team which means keeping have no use for the team. The Napoli management will reduce the money if no team is willing to pay that amount and I am sure Osimhen will not go to Sausi Arabia.
The Napoli management and Conte know very well that Osimhen will not want to stay with Napoli for long. Osimhen is a talented player. He would like to play with higher wages and better squads. Moreover Napoli management also target to earn money by selling Osimhen. Osimhen was bought by Napoli management for a huge sum. So naturally Napoli management will want to profit by selling Osimhen. This is why Antonio Conte is now interested in Lukaku.
Napoli management wants 130 million euros for Osimhen. Several clubs like Arsenal, Chelsea and Manchester United were interested in adding Osimhen to the squad. But with a release clause of 130 million, not many clubs are interested in adding Osimhen to the squad at the moment. Now there are rumors that PSG management are interested in adding OSimhen to the squad. I still don't know if this is true. But PSG have plenty of money. This news is more likely to be true. Because PSG now need a worthy replacement for Mbappe.
