That's right, Luis Enrique needs to recruit new players in the next transfer window to fill the positions left by Mbappe, Osimhen and Rahsford are worthy of being PSG main targets when the transfer window opens. Luis Enrique can update his strategy to suit the depth of the squad he has, of course it will take a little time to adapt. Meanwhile, PSG will continue to dominate Ligue 1 even though Mbappe officially leaves, they are too powerful for other teams.
What happen to PSG performance this season? They're not playing as if they're professional, more comparable to average teams. PSG have numerous players on their radar, they will not be sitting back and watching other elite teams taking over the transfer market without them been involved. PSG will never hold out but put themselves up and running. Luis Enrique have always implemented straight winning techniques for his team but he doesn't sit in the position of signing players, rather the team's president, Nasser Al-Khelaifi have estimated capacity of making crucial signings on any player he picks interest.
PSG does need new players to replace Mbappe but they don't have to get players who have equivalent performance to Mbappe.
Now we can see that PSG doesn't have any problems winning the league 1 title even without Mbappe, PSG will still dominate league 1 just with the existing players and that's all because the players that PSG has are of higher quality compared to other teams.
Bringing in Rashford or Osimhen will not be that easy when Napoli and Manchester United are both in bad shape and need help from these reliable players to get good results in the next season.
I think PSG will not be able to get Rashford or Osimhen this season or may have other alternatives.
