It is so great to hear that Lyon are officially staying in the Ligue 1.

I was really sad after hearing that PSG's paying for Barcola's remaining installments upfront might not be enough.
By the way I wonder whether PSG is planning to sign a striker this summer. There is only Gonçalo Ramos now. Kolo Muani is also returning from his loan though but I don't think he will stay. I don't expect them to rely on Ramos honestly. They have been using Dembele as CF too but I don't know if Luis Enrique is planning to use him like that all the time. Is there any recent rumour related to a striker signing by them? I feel like they will go on like this...
If they're going to sign a striker, perhaps Osimhen or Gyökeres would be a good option. However, I don't think they've made any moves on Osimhen because I've never heard of him in a transfer window. In my opinion, Paris Saint-Germain needs a transfer. With two strikers, they could easily win both the Champions League and the French Ligue 1, rotating. I think we could see a few signings from Paris Saint-Germain before the transfer window closes.
For the mean time they're focused on qualifying for the finals in the FIFA Club World Cup then probably win maybe after they win it or if they're out they'll then focus on increasing their depth. I don't think PSG is interested in any of those players you mentioned else they would've shown interest on Osimhen especially since they can afford his wages and he'll strengthen their attack. As for Gyokeres it seems Arsenal is his final destination this summer except PSG decide to show Interest.
