ABU DHABI -- Sebastian Vettel has admitted his season was not up to the standard he or Ferrari expected in 2019.
Vettel left preseason testing as one of the favourites for the title, but finished the year fifth in the standings behind teammate Charles Leclerc, Red Bull's Max Verstappen and both Mercedes drivers. He made race-defining errors in Bahrain, Canada, Great Britain, Italy and Brazil, and won just one race in Singapore after Ferrari's race strategy played into his hands.
Vettel's Ferrari contract expires at the end of 2020 and the four-time world champion says it is important he ups his game over the course of next season.
