Let's put aside Lukaku age for now, because statistically the comparison of his goal productivity with Osimhen is not much different where Lukaku in the 2013/24 Serie A season in 32 matches bagged 13 goals and 33 assists while Osimhen in the 2023/24 Serie A season in his 25 matches with Napoli bagged 15 goal and 3 assists.
However, releasing Osimhen from Napoli was a very inappropriate decision, because so far Osimhen role has been very vital as the spearhead of the attack. Although I admit that last season Napoli was better because they managed to win the title, while this season dropping to 10th position shows bad results.
The reason is that Conte has a point of view that is often annoying, so if he becomes Napoli coach, Osimhen career could be threatened.
Releasing Victor Osimhen and having new striker is normal as we are now having new coach at the Napoli after having worst end of the season which bring too much decline in quality and having no consistency after winning title with this all happen due to management level mistake which bring serious trouble and team gone in deep trouble after this all, but now they are working to bring back themselves at the better spot which they deserve in Serie A.
Antonio Conte and Romelu Lukaku have good relationship while these both already work and achieve better results, so things can take good change here as well. Romelu Lukaku is having good depth in last few seasons with he can shine under Conte here at the Napoli which could be good for them because we can expect better results and improved performance which is also important for them for having success.
I hear the Conte and Lukaku optimism, but don't get carried away. Their past collaboration doesnt guarantee success at Napoli. Lukaku has had his moments, but can he regularly score Napoli's goals? Osimhen showed great potential despite his circumstances. It seems shortsighted to dump him after one bad season.
I think Napoli could utilize Osimhen's transfer money, but sacrificing long-term potential for a rapid financial injection is risky. Also, Chelsea may not want to sell Lukaku. If they do, he'll be expensive. Before making a hasty decision they may regret, Napoli should consider all options.
