Sebastian Vettel says he looks at his six years with Ferrari as a failure after he missed out on winning the Formula One championship with the team.
Vettel joined with high expectations in 2015 but, despite 14 wins over six seasons, was unable to win a fifth world championship to add to the four he secured with Red Bull.
He came closest in 2017 and 2018, when Ferrari appeared to have a car capable of winning the title, but never entered the final round with a shot at winning.
This weekend's Abu Dhabi Grand Prix will be Vettel's last race with the team before moving to Racing Point for 2021 ahead of its rebranding to Aston Martin.
