Sauber are still yet to confirm Marcus Ericsson’s team-mate for the next campaign although recent reports have claimed Wehrlein is close to being unveiled.
This is largely down to the fact Felipe Nasr, who has been in talks over the final seat, has had his sponsorship stopped by Banco do Brasil, and the lack of financial backing is a huge concern.
Recent reports had claimed Manor’s Wehrlein had agreed to sign for the Swiss-based outfit, but the 22-year-old says that is not the case.
“Yeah, it’s not true,” Wehrlein said. “There’s no news. There’s still talks and discussions going on and, of course, with both teams because they are the only teams with a seat left for next year.
“Many people asked me today about if it’s true that I signed and no, it’s not true.
“It’s not good that people write something like that when it’s not true. If it would be true we would confirm that.”
Wehrlein is yet to extend his contract with Manor and his future for the 2017 season is still up in the air.
Southampton have announced plans for a two-week tour of China as part of their pre-season preparations for the 2018-19 season.
