Osimhen has made a big mistake because when he was still with Napoli, Chelsea was very interested in his services at that time but he rejected it. That's what made him join Galatasaray which reduced his fame because he played in the Turkish league. But this season he stole the attention again because he got an offer from Al Hilal with a very large salary, I think he should accept it because this is an opportunity for him to earn a lot of money.
The main problem behind Osimhen transfer last season was because of their misunderstanding with the Napoli team, the team demanded a huge sum of money for him to be released, while other teams are pricing less; the player wanted to leave at some point, but many bids were rejected by Napoli because they are demanding much, and they removed him from their squad list which means they don’t need him for the season, and they are demanding high money for him to be sold out, that was why almost all teams back off, and Osimhen was looking for where he can go just to play, then he went to Galatasaray on loan, and he has helped the team to win the Turkish league with a golden boot award for himself.
But we'll see, whether Osimhen will take the opportunity to earn a lot of money or he will stay in Europe to realize his dream of getting a prestigious trophy in his career. I see Manchester United also want to bring him in, but their hopes are so small.
If no better offer come for him from any top European team, he will save his football career by signing for Al Hilal because he can’t stay where his effort will not be appreciated. He will definitely leave Napoli this window for another team,l. If he join either Chelsea or Manchester United, he will have a better season because they both need him and they have similar style of play.
