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.
Why is it misinformation? We do not know what happened that part is true, but it could be a fight between Conte and Osimhen that caused this, we wouldn't know, it might be true or it might be wrong and we have no idea which one it is.
This is why we should not be really saying it's a lie that they had a fight, it might be a lie or maybe not. In the end, Osimhen left, that is what we know and have in our hands and we should not be really considering that any further, there is no way to get him back, he is gone. And I also believe that he is not going to play for Napoli ever again, he is out on loan right now, and when that loan ends he will go play for some other team as well, so we are going to see them be very happy anyways.
