Mercedes boss Toto Wolff has acknowledged Vettel’s availability, but also made clear that the priority for 2021 will go to the team’s incumbents and its protégé George Russell.
“I talked to Seb and of course we went through the variations and possibilities at Red Bull,” Marko told Sky Sports in Germany.
“Those unfortunately don’t exist and I think the understanding was Seb would continue if he gets into a winning team and that would be Mercedes in this case.”

But Marko suggests that a plush retirement is most likely on the cards for Vettel.
“He is a four-time World Champion who has achieved a lot in this sport and who is in a good financial position before he takes on any midfield team.
“I would also say that it would suit Seb’s character, his style, to stop.
“It would be a shame for the sport but for the person Sebastian Vettel, it would be the best solution if no winning team is available.”
