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.
Even though PSG doesn't sign any striker this season, they will definitely win the French Ligue 1 title easily because no club in French Ligue 1 can challenge PSG for the French Ligue 1 title. The PSG team is still in good shape, and since Luis Enrique hasn't shown any interest in any player, we can't really tell if PSG will sign any player this season. If Luis Enrique wanted to sign either Victor Osimhen or Gyokeres, he would have signed either Victor Osimhen or Gyokeres before now, and both players are close to signing for another club, so I believe Luis Enrique will not sign either Victor Osimhen or Gyokeres.
