According to Bild, Vettel has not signed a fixed long-term contract with Aston Martin, and there is an option in the contract that allows Vettel to opt out of the contract and leave after the 2021 season.
However, Vettel told German media RTL: "The goal is not short-term, but for a long-term cooperation."
The 33-year-old Vettel admitted that he thought hard about simply retiring before agreeing to the deal to race with the current Racing Point team that will be rebranded as Aston Martin in 2021. There, he will replace Sergio Perez.
