Four-time world champion Sebastian Vettel believes Michael Masi should remain in his role as Formula One race director despite his controversial call that effectively decided the 2021 world title. Masi's position is under intense scrutiny after he was accused of bending the rules to allow Max Verstappen the chance to beat Lewis Hamilton to the title following a late safety car period in last season's finale in Abu Dhabi. But Vettel, a director of the Grand Prix Drivers' Association, has thrown his weight behind the under-fire Australian. "For Michael, it has been a pity," said Vettel, speaking at the launch of Aston Martin's car for the 2022 season.
