Valtteri Bottas has expressed strong confidence in remaining with Sauber for the 2025 F1 season, stating he is '99%' sure of staying amid ongoing discussions about his future. He emphasized the importance of his experience as a seasoned driver competing against teammate Zhou Guanyu and potential rookie Gabriel Bortoleto for the remaining seat alongside Nico Hulkenberg. Bottas noted that while negotiations are progressing positively, many details still need to be finalized to ensure both parties are satisfied. He acknowledged the challenges posed by Sauber's poor performance this season, which has left both him and Zhou at the bottom of the drivers' standings. With the team's impending transition to Audi in 2026, Bottas remains hopeful that improvements to the car will allow him to showcase his capabilities next season. However, he has also admitted to contemplating the possibility of leaving F1 if he can't secure a seat, making his future uncertain.
