I think it should be another coach. The first name that comes to mind for me is Jose Mourinho. He had success even with limited opportunities in Rome and won the conference league cup, while losing in the final at the UEL this season. I am sure that he will have successful matches in Paris SG. I hope they convince him and we can follow him as coach at the beginning of Paris SG.
Mourinho is unlikely to go to PSG, he is preparing Roma by making several player sales and also wants to bring in new players. Enrique is indeed the strongest rumor because rumors have been that negotiations have been carried out and all that remains is to wait for an agreement on both sides. Previously there was also news regarding PSG wanting Arteta to go to France. but it looks like it's just a rumor.
