Concerning whether his move to Chelsea will benefit him or not, it will because none of Chelsea's current attackers are as excellent as him, and he will not be left on the bench or played as a second choice striker after spending so much money on him. So his career there will be wonderful, and won’t be a wrong move to his career.
After the mistake, Napoli posted a stupid thing. Maybe that could be one of Oshimen's reasons for leaving. I think he won't regret it when he leaves. At such a young age, he deserves to go to another club in search of valuable experience. Actually, Chelsea already has a very luxurious squad. They bought very expensively, but could not adapt well to the EPL game.
