Sauber driver Wehrlein plans talks with Wolff, Vasseur on F1 future

Wehrlein's deal with Sauber expires at the end of the season, and the Swiss team is expected to give Ferrari junior driver and Formula 2 champion Charles Leclerc one of the seats for 2018.

Wehrlein, team-mate Marcus Ericsson and Ferrari junior Antonio Giovinazzi are in contention for the second seat.

Meanwhile, Wolff is pushing Williams to take Wehrlein alongside Lance Stroll but the team is in no rush to make a decision as it continues its evaluations of Robert Kubica.

"I'm planning to speak to Fred and Toto in the coming days," Wehrlein told Autosport.

"There was no news before the weekend but maybe there is some new information from this weekend so let's see."

He added: "I spoke to [Fred] in Japan and he said it's an option for me. I don't know how much Ferrari is involved in that.

"It's [the Sauber drives] between the Ferrari drivers, Marcus and me."

Williams ideally needs one of its drivers to be over the age of 25 as part of its arrangement with title sponsor alcohol brand Martini.

However, there is room for negotiation on the issue should the team decide he is the best option.

"I think Toto is still talking to the team [Williams]," said Wehrlein.

"He's talking to everyone who could be an option, including Williams.

"Definitely yes," he added when asked if Williams would be a great next step for his career.

"Williams has a great car at the moment, they are fighting for P5 so it would be a big step for me.

"At the moment, I'm at Sauber and I'm thinking about Sauber and what we can do here in the next four races."
