Franz Tost does not believe Sebastian Vettel will win a fifth world championship after switching to Aston Martin. But Alpha Tauri boss Franz Tost, who was also in charge when Vettel won his first race at Toro Rosso in 2008, doubts it. “I hope and wish for him that he will be successful and able to win races,” he told AvD Motorsport Magazin when asked about Vettel. Former driver Christian Danner agrees, telling Sport1: “This is a team that drives in the midfield and will be taking on Franz Tost’s team. “But if he likes to race, then he should keep doing it.”.
