It would definitely be interesting to see Ronaldo and Messi playing for PSG. But even if Ronaldo really joins them, we don't know whether Messi would decide to stay here too. But I think he will stay for one more season as long as Barcelona don't make an offer and meet his demands. If these two legends have a good relationship with each other here, then PSG might be very successful next season. But let's just wait to confirm this first.
