Nico Hulkenberg has already been signed to the project for next season ahead of Audi's transition, for example, with the German driver making the move from Haas at the end of 2024.
Plenty of other names have been touted to sit alongside Hulkenberg, including Mick Schumacher, Franco Colapinto, and Gabriel Bortoleto. However, it now appears that the team could settle on another option.
According to German publication Bild, the Hinwil-based outfit have made their decision on who will partner Hulkenberg, at least for 2025.
Former Ferrari team principal Mattia Binotto is currently in charge of trying to find the right fit for their project, as the chief technical officer of Sauber Motorsport - soon be Audi.
Alongside outgoing Red Bull sporting director Jonathan Wheatley, they hope to bring the team into contention for podium finishes in the future, becoming a bigger threat in the F1 world under the German manufacturer's name.
At least in 2025, Sauber reportedly see the driver to do that best as Bottas, whose current deal is expiring at the end of 2024, but who they have 'decided' will be in the car next season.
Bottas will reportedly be offered a maximum two-year deal, with the opportunity to axe him after one year if his performances do not pick up from their current level.
It means that Schumacher, son of seven-time world champion Michael Schumacher, is set to spend another year away from the F1 grid following his departure from Haas in 2022.
