Victor Osimhen is a player of Nigerian descent who is still 25 years old, a fantastic player with Napoli last season, and this season Napoli are in poor form and Victor Osimhen's performance is also declining, last season many teams were interested in him but he chose to stay at Napoli and this season Victor Osimhen doesn't yet know where he wants to go, whether to stay or leave, but currently there is no club he has been linked with who could reach a deal, let alone Chelsea who were very interested in him but in the end they dropped out of the hunt for the player.
25 to 27 years old is best time in a player career even recent years, we are witnessing prolong of player career lifespan from Ibrahimovic, Cristiano Ronaldo, Pepe but after 30 years old, it's really difficult to predict what will happen next years. When a player passes his 30 years old, his body might become weaker and more sensitive with injuries. If he is unlucky, a serious injury can destroy his career and a famous example is Marco Van Basten who retired at very young age after an ankle injury with AC Milan.
Osimhen must make his decision to move if he want to win big titles. Napoli will never can give him such chances to win big titles in every season.
However, Conte's arrival at Napoli is an extraordinary thing for him because we know that Conte is a coach who has a lot of experience in training players, and of course Conte's arrival will make him develop further under his guidance I think the decision to stay for one season is the right choice. good for him, to improve his performance again so that his clause can increase again.
Conte is a confusing coach and he often succeeds with his clubs at a first or second season but he is similar to Jose Mourinho, after two seasons, he often starts to conflict with players, staffs, boss and relationships between him and players, staffs, boss turn to be broken and unfixable.
