In my opinion there is a big difference between these two players and I say that Victor Osimhen only got extraordinary achievements last season whereas previously at Napoli he was only able to score no more than 20 and last season he was able to score more than 20 but in this season Currently he is experiencing a deep decline, only being able to score 7 scores in 13 matches.
Meanwhile, if we compare it with Mbappe, it is actually very far away and Mbappe's performance is stronger than Osimhen's, as proven by the scores he gets every season, he is always able to score big and this season he has scored 20 scores from 19 matches.
For me, it's a bit risky if PSG management thinks about replacing Mbappe with Osimhen because even though he has gotten big scores, I'm worried that Osimhen will experience a decline in performance and not be able to appear as strong as Mbappe.
Osimhen is unlikely to be able to replace Mbappe. If anyone replaces Mbappe, it will be Holland and yes, why take Osimhen if there are already two strikers of his level. An alternative option for the French is Marcus Rashford from Manchester United, but PSG has no doubt that he can arrange the transfer of Osimhen. The Parisians are looking to pay about 80 million euros for him. And in comparison, Mbappe scored 31 goals and made four assists for PSG, and Osimhen eight goals and two goals for Napoli, which is in a crisis in the game.
In my opinion, Osimhen is not really stable as a player, it's not bad but his performance still fluctuates and that's with a very high graph, while Mbappe has so far been consistent with his performance, so it's not surprising that Mbappe is more valuable for Paris Saint Germain compared to other players , like Osimhen. However, if Paris Saint Germain really loses Mbappe, then it might be an option to be on their recruitment radar. However, so far I have not heard any further news whether Paris Saint Germain is interested in Osimhen or not.
There are many plyers who could be part of Paris Saint Germain, but the question is whether they will be like Mbappe or not, because now Mbappe is really influential at Paris Saint Germain, he can be a differentiator from the matches played by Paris Saint Germain.
