Simons has made himself develop at RB Leipzig and he is in the spotlight of many clubs to bring him from PSG because Simons has not yet found a place at PSG, with many clubs interested in him, one of which is Munich which is very ambitious to bring him in. This is a good thing for him because he can develop with a team that has good performance and also the Bundesliga is better than the French League and with this he can decide to leave PSG and work with a team that really wants his performance.
PSG is very confused about getting good players for next season too, and I think PSG must think more carefully if they want to release Simons to another team. Because PSG still needs to think about other players they have to bring to PSG after Mbappe's departure to Real Madrid and if Simons is also released to another team, of course that will add more burden to PSG in finding a replacement. Because currently it is not easy to convince players to move to PSG unless they are offered a higher salary.
In fact, PSG will not have any significant difficulties in bringing in new players, who can replace the role left by Mbappe, because financially they are very stable. Quality players clearly demand high salaries, which is how the football industry works at the moment. PSG actually has an attraction in the eyes of European players, apart from being able to provide high salaries, PSG can give them the opportunity to experience the Ligeu 1 trophy every season. Apart from that, it is certain that they will play in the Champions League too, this is something interesting about PSG, which perhaps not all elite European teams can get every season. However, competition within the PSG squad is also tight, even though Mbappe has left, that is a fact. Squad overhaul due to frequent manager changes may be a more reasonable reason, when some players are reluctant to join PSG.
