Osimhen has become a burden for the team lately, he fell out with De Laurentiis and later with Conte, who suspended him from training, so for discipline in the team they had to get rid of him. Lukaku has fit in very well, you can see that he is trying very hard, he likes working with Conte and that was their original goal to get him in the team. If Napoli, Inter and Juventus keep up the same pace until the end of the championship, maybe we will have something like competition in Serie A.
I don't know what has happened between the club president and Victor Oshime but, saying he fell out with Antonio Conte is nothing but misinformation truthfully. They had talks together but Victor Oshime stated he wants to leave the club, Antonio Conte even came out to say that he will not get involved with whatever that happened last season. I hate the comparison between Victor Oshime and Romelu Lukaku, check the stats and you'd see that having Victor Oshime in your sqaud is a great thing. Well, I'm rooting for Napoli to win the Seria A Scudetto League Competition.
