Enrique can definitely find a replacement for Mbappe as a striker at PSG next season, but we will probably see an announcement because there are still many young players who are quite productive and have the potential to become good players who can compete next season, although there may not be any players who have Mbappe's abilities. but at least it can fill the void in PSG's main squad, perhaps it will take more time for Mbappe's replacement to adapt to the existing players because players are needed who have good experience in adapting quickly to a team.
I haven't seen PSG's plans to buy players and look for a replacement for Mbappe in his position as striker but I think Enrique certainly wants to find the best one who at least has the potential to play the way he wants and the team, it's time for PSG to learn to let Mbappe move to Madrid and that's it. every decision he has taken to play with Madrid next season must be respected, I think PSG must immediately look for replacement players because the sooner the better to prepare this team well so that it can become a strong team like before.
I hope Enrique can get talented players who can strengthen the PSG squad, especially in the front line, I still miss the time when there was still Zlatan Ibrahimović at PSG. because in my opinion he is a very good striker, with PSG currently losing one of their quite good strikers they definitely have to look for a replacement even though it may not be comparable but what you said is true at least it can still fill the void in the PSG squad. with the loss of one of the players in their attack line and if PSG has not found a better replacement, I think PSG will experience a decline in performance, this is just a prediction but I hope PSG can perform better next season with the surprises that will be given.
Apart from that, if they succeed in getting new players, of course they need time to process adapting to each other to get to the best point in their performance. No matter how good the players they get to replace Mbappe, of course there will be an adaptation time process, it is unlikely that they will immediately be able to show their best with their new players.
