They are already feeling the pressure of not being able to do well in the Champions League. PSG may be the only team who chased the Champions League a lot and despite trying hard to win the Champions League title, they could not win the Champions League title, on the other hand, they are constantly winning the local league title despite not thinking much about the local league title. This season they are at the top of the France League points table and if they perform like they are, they will surely win the France League title this season as well. The crown of European excellence is the Champions League title that PSG has yet to claim. But even if they fail multiple times, I believe they will try again and once again they will put together a good team to win the Champions League title.
You're right, for me the solution is to look for new strikers , those strikers who can make the difference. It is said that Mo Salah wants another challenge, Rashford is available, so Luis Enrique can and has the means to ask for any player because in that club what there is most to do is money, so he must be broad in his requests, not limit himself, because it is the club that needs material to be able to perform well. At the moment I think they can go much further if in the transfer window they move in search of the best strikers available. He has to convince them because that is the only solution I see for PSG.
