Lukaku is a good enough player for me. There are several reasons why Conte is interested in Lukaku. Lukaku has previously played in Conte's squad. So Conte is well aware of Lukaku's capabilities. If Conte can use Lukaku properly, he can serve the Napoli team well.
Moreover, Napoli management is interested in selling Osimhen. Because selling Osimhen now will allow Napoli management to earn a large amount of money. Also, Napoli is not a club that spends big amounts of money to buy players. This is why Conte now wants to add Lukaku to the squad.
If we look at Lukaku career so far, of course we cannot deny that he is one of the great strikers who has ever existed, but the phase he has faced in his career so far has certainly not been easy and has made him ups and downs in his performance, even though he is now is no longer young but in fact he is still very suitable to be used as the main striker for a club, Lukaku has played in several different leagues so far in his career and it seems like Serie A is the most suitable league for him, currently Lukaku is still one of the players that belongs have chelsea and reportedly Chelsea are also starting to offer Lukaku to other teams in order to get some money at this time. Previously, Napoli and Chelsea wanted to exchange players between Osimhen and Lukaku but Chelsea refused after seeing that the amount they got from the deal was very small.
Currently, Napoli is still looking for a team that wants to buy Osimhen and Napoli are even willing to reduce Osimhen current selling price to 100 million euros from the previous 130 million euros, although Osimhen has been an important player for Napoli in the last few seasons but Conte doesn't want to keep him in the squad at this time and actually asked Napoli to bring Lukaku from Chelsea as their main striker next season, the sale of Osimhen will of course provide huge profits for Napoli and that the money can be used to strengthen Napoli in next season.
Romelu Lukaku used to be one of the best strikers in Europe in the past and still posseses those qualities that made people consider him as one of the best. His ability to bully defenders, get past them and always cause unrest among opposing defenders are some of the reasons he's been feared. Last season he was signed on a season long loan by AS Roma and despite all his efforts, he was unable to reciprocate the same number of goal contributions he had with Inter Milan the previous season. Without trying to write off the Belgian striker, I strongly believe that he's past the peak of his career but that doesn't mean that he can't still deliver of well managed.
Chelsea have always deemed Lukaku surplus to requirement at the club in the last three seasons which is why he's been out on loan despite having a running contract with the English Premier League club. If Napoli is interested in Lukaku, the best Chelsea can do is try add Victor Osimhen to the deal so the Nigeria striker can move to the London club while Romelu Lukaku joins Napoli
