Just before you make a conclusion about lukaku been the best replacement and a deadly bomber, let's take a stroll down memory lane, at Roma where lukaku was, where he was loaned out by Chelsea, there wasn't so much of an epic or incredible performance from him even with the presence of his former Chelsea boss Mourinho, he wasn't too exceptional, he was a little above average so it will be safer if our expectations are more realistic than been a hyper one. I believe he is going to do well reuniting with his former boss back in Napoli but you should also know as it concerns the records, osimhen has an incredible record, one which cannot be easily overturned in Napoli so I wouldn't be so quick to seeing lukaku as a match.
When there is a choice between the two players I will choose Osimhen who deserves to be the best player and the player who deserves to support Napoli. And if it's about the comparison of the two players, Osimhen future is much better than Lukaku whose skills are decreasing and actually Lukaku is only favored because he has a big body. While Osimhen has skills that can provide the best contribution to the team. I'm not saying Lukaku is bad but in terms of facts and logic, everyone will definitely believe more in Osimhen future. Maybe some people will support Lukaku no matter what because they might be part of the player's fans or even Napoli fans and I understand that anyone is free to favor Lukaku but I agree with you more if you think logically it would be better to believe that Lukaku contribution will not be as good as Osimhen.
