PSG hasn't sold any player this summer. They have even made their first signing recently. Like I said before, the GK Chevalier. Do they need more depth in the squad? I don't know... Maybe a new RB? Mukiele's return is unknown on Transfermarkt. If he is out for months then it might make sense to bring a new player there.
PSG might be interested in signing Rodri, but that doesn't mean that Rodri will go to PSG. City needs him more and wouldn't let him go to PSG. The absence of Rodri affected the club a lot last season. PSG should know that no one can predict what will happen next season. They should have at least sign one or two players to add to the team for backup incase of injury.
I haven't heard of any linking with PSG when it comes to Rodri. His name has been called with Real Madrid. But
Fabrizio Romano said today that they aren't interested either.

He had a serious injury period you know. I understand these teams' concern.
