Read the post a few hours ago and it's quite unfortunate that there are problems that eventually arise between players and clubs because of posts on social media. I think Napoli's social media is managed by a special person as an admin and he should be wiser when making posts about his players, whatever the purpose. even though it's just a joke because people who see the post can have different responses. If the intention is to make fun of him because he failed to take a penalty then that is even worse and in fact many players have also failed to take a penalty kick.
It would be quite a shame if the relationship between player and club ended because of a post on social media and if Napoli feel they really need him then apologizing publicly is the best way unless they no longer want this player.
In the match against Udinese in a few hours we can see if this problem has been resolved with Osimhen playing for Napoli, if he doesn't play I think he will leave this club soon.
Napoli as a whole are just ungrateful and is bad to do this to someone who spent every single strength he have left to make sure he plays out his best not just for him to be the best but to remove that shame from the faces of Napoli fans by helping them to win that title last season. And with all these happening I believe that Napoli will struggle to get to that height they were last season. No amount of apology will remove this mockery from the Nigerian striker. After apologizing they still went as far as to humiliate him publicly. I always wanted him to make a move after winning the title with Napoli but he thought staying would show how loyal he is to the club.
