The real issue is that if he didn't really cut ties with the team, he could have been a marvellous striker for them, he could have been awesome, and there is no denying that he would be great for long term. However, we need to remember that he had damaged his relationship with the team so much that he was basically left out of the squad, if he stayed with the team then he wouldn't even be playing.
Even with Lukaku on the team, if Osimhen was good with the team and the manager he would have still played, but because the damage was beyond repair, we saw him sent on loan. They are not paying his salary and he will be let go whenever an offer is made. Plus they made a new contract, basically a longer one, but cheaper release clause, so it should be fine for him to leave now.
The best thing for Osimhen was that he left the team to join another team. If he stayed back, it would have been his worth nightmare throughout his career. For a player like him, he can still fit into Conte’s style of football and become successful more as a striker in the team. He is left behind because of his differences with the team. He shouldn’t have had a problem with the management, Conte could have still used him and he’ll be productive now.
The Serie A is becoming one of the best leagues in Europe in recent times, with so many teams fighting for the league title every season. The performance of one always differ from the other teams season by season and that’s to show how every team in the league are trying to be their best to be victorious in the end. The team is now worth the praise they’ve received since the year they took the Scudetto. They’re back now to fight for the title once again.
