It is very likely that Enrique will try to find replacement for Mbappe, but there is no certainty who will really be worthy to replace Mbappe in the PSG squad considering that they are team that has great players who really retain them.
If Enrique doesn't immediately look for player who can replace Mbappe, I also doubt that PSG will be able to play well, especially in an important competition like the UCL.
Luis Enrique did not just choose a player to replace Mbappe, he will try to bring in a top player who can be relied on and has sharpness in scoring goals. PSG is not experiencing financial difficulties because this club has abundant funds to recruit players. Several names have been included in PSG shopping list in the transfer market. Currently, Osimhen name is at the forefront of what PSG is pursuing. Rashford was also rumored to be a target for PSG because he was thought to be able to blend in with the tactics used by Enrique. PSG must succeed in formalizing several new signings to strengthen the team next season, the Champions League is still their main target, but if there is no improvement in the squad, it will be very difficult for PSG to win the trophy.
Enrique is a coach who has good achievements and also has extraordinary experience, and losing Mbappe is not the end of the story at PSG, because we know Enrique is a coach who does not prioritize star players, Enrique and PSG currently do not have players who have been discussed by management themselves PSG to help Enrique compete next season.
PSG has a lot of potential in its own academy, it would be good for Enrique to develop the existing players and not waste too much money just targeting Mbappe's replacement, because that will be difficult, as is the quality that Enrique has in training These players are important for him to be able to bring young players to become the best at PSG next season.
