This is despite Sainz claiming two stunning victories in 2024, and providing a real challenge to team-mate Charles Leclerc during race weekends.
Sainz has the opportunity to go out on a high, with Ferrari's recent pace making race victories possible, as well as the team challenging for what would be their first constructors' championship title since 2008.
Ferrari searching for a new driver?
While the two main drivers for 2025 are settled in Hamilton and Leclerc, Ferrari's reserve drivers are both due to start new positions in 2025.
Zhou has failed to score a single point throughout 2024 in a struggling Sauber outfit, and is highly unlikely to get another full-time seat on the grid in the near future.
Italian media reported that Ferrari were therefore planning to give the Chinese driver a second chance, acting as a reserve driver for Hamilton and Leclerc.
However, a Ferrari representative has now confirmed to GPFans in an official statement that there are no plans for Zhou to join the Scuderia as a reserve driver.
