I wouldn't believe SPORT if I were you. They have a knack for reporting false news all the time. Most of the stuff they report all the time is false and I'm almost certain this is false too.
There was no real interest in Osimhen from Arsenal. If there was we would have known of it and other news channels would have reported it too the same way we all knew about the interest from Chelsea.
Having anger issues is bad, but I feel it's actually exaggerated a bit. Aside from Finidi, I have not heard of Osimhen having or causing any issues in the locker room or disrespecting his managers. If a club really wanted him, I don't think that would be an issue. People like Diego Costa, Arder Turan and Balloteli were still employed
I also doubt the authenticity of the news and if Arsenal have shown interest in Victor Osimhen it must have leaked somehow even if it was just a rumor. When teams came for Osimhen we all knew about it even when Saudi teams came it was everywhere, i doubt if Arsenal was willing to pay that much for Osimhen, they are known to be a team that can’t pay much for players.
There are certain levels you reach as a player that you will react to some coach decision and what transpired between Osimhen and Finidi, i think the player was disappointed and hurt that he couldn’t hide his frustration despite giving all for his National team. As a coach the way you address your players is how much respect they will give in return. Osimhen might have reacted to some coaches but they were all out of frustration and i don’t think he is that kind of a player and that shouldn’t be a reason why a team would not want his services.
Regarding the striker's disagreement with coaches, he had one with former French Napoli coach Rudi Garcia. The Nigerian reacted angrily at the coach when he was substituted.
The reason for the post is not to criticise the player but to derive some lessons. Some of the players you mentioned would have achieved more if they were well-behaved. Every coach will not sign a disrespectful player if they have other options.
Reacting angrily when subbed off is common among big players, Ronaldo have done it, Messi too have done and so many star players so Osimhen case is just being exaggerated.
Compared to Ballotelli and the above mentioned players i don’t think Osimhen is as disrespectful as any of them and that was why Chelsea didn’t hesitated when trying to bring him to Stamford Bridge, his anger is a controllable one.
