Osimhen was an option for PSG even in the last season. I think Osimhen could have even better performance in the last season when he was in the better form but now PSG knows they can't expect to see a miracle from this player but he can have a good performance like two years ago and he can be out of the good form like last season. I think there can be better options for PSG than Osimhen and they should not be worried and run for finding a replacement for Mbappe because Osimhen and Mbappe are not at the same level at all.
Osimhen's performance when he brought Napoli to the Scudetto was of course extraordinary and that's why previously PSG was very interested in getting him, but I think we all agree that there is no guarantee that a player can continue to be on fire every season and that's what happened to Osimhen Currently, Osimhen performance and goal productivity this season has decreased and he was only able to score 15 goals for Napoli, but the decrease in the number of goals occurred because he suffered an injury and was absent from playing for Napoli after Nigeria called him to play in the African Cup, but for now Osimhen is still is the right option for PSG if they want to find another striker who is worthy of replacing Mbappe.
Osimhen was able to appear quite prominent in Serie A even though he had to compete with great strikers owned by rival teams, but if he departure to PSG next season of course I'm sure he will be able to immediately top the top scorer position in Ligue 1 like when Mbappe replaced Cavani in PSG attack line, to be honest, at the moment it seems difficult for us to compare the level and quality of Osimhen and Mbappe considering that the differences in competition in Ligue 1 and Serie A are quite contradictory.
