Without Messi and Mbappe, PSG's attack will face some problems. Neymar is a good player but his fitness is not good. So PSG cannot rely on Neymar's performance. Luis Enrique must find alternatives to Mbappe and Messi. And it has to be done very quickly. Will Harry Kane be interested in coming to PSG? I don't think Harry Kane will come to PSG. He will want to join a better team. It is still uncertain which players Luis Enrique is looking to bring in to bolster his attack.
With the money PSG have they will be able to buy whoever they want although of course the results will not always be as expected, Harry Kane seems to be closer to Bayern Munich, Victor Osimhen can be the next striker they can look at especially this player is younger than Harry Kane so he can play longer at PSG.
If Mbappe is really going to leave Ligue 1 because Luis Enrique has experience at Laliga it is very possible that PSG will buy players from Laliga based on the advice of his new coach and he is not a striker whose name is always said to be going to PSG, because anything is possible, but as long as Mbappe is still at PSG the opportunity for this club to find another striker may be postponed unless they are looking for a second line striker because of the busy schedule they will have both domestically and in Europe.
Since Luis Enrique is the coach of PSG, I think he will give more priority to Spanish players. Because he has been with this team for a long time. And he is more familiar with the players in Spain. I guess we will see quite a few Spanish players in PSG's squad next season. But Victor Osimhen is an excellent player. He is capable of scoring a lot of goals if he is with a stable squad. PSG will surely benefit if Luis Enrique adds Victor Osimhen to the squad. Victor Osimhen can be a worthy replacement for Mbappe.
