Ricciardo's current role is team mascot. There is no way he returns to Red Bull and anyone paying attention can see it. He's there to drum up views on the socials.
He left in the first place because he didn't want to be second to Verstappen. And he failed at being the lead driver at both Renault and McLaren. With McLaren choosing to go after rookie piastri.
Unless Ricciardo gets desperate and accepts the Haas offer. I don't think we'll be seeing him on the grid anytime soon.
