Sauber has yet to announce who will replace former team boss Monisha Kaltenborn who left the team in the week leading to the Azerbaijan Grand Prix.
The Swiss outfit has apparently short-listed several indivuduals, including ex-Manor men Dave Ryan and Graeme Lowdon, ex-McLaren CEO Jost Capito and former Renault boss Frédéric Vasseur.
The latter appears to be the most probable choice at this stage, with the Frenchman seen visiting the team's Hinwill base two weeks ago.
Neither Pascal Wehrmein or Marcus Ericsson could offer any insight in to Sauber's choice or when it may be announced.
"Of course it’s different without a team boss, and Monisha especially," said Wehrlein.
"If there are some decisions to be made, Beat [Zehnder, team manager] or Jorg [Zander, technical director] will decide.
"It will be the same this weekend until we have the new team boss."
Ericsson said he was also in the dark, and did not feel the need to get involved in the matter.
"As a driver it’s important for me to focus on my things," he said.
"What’s happening above me, I don’t gain anything putting energy or stuff into that.
"I was in the factory to have meetings with the engineers and the aero guys to focus on the things I am involved in and can make a difference in.
"Hopefully soon we have a new person in this position that can put their touch on the team. That would be great."
