Sebastian Vettel has given a damming verdict of his 2019 campaign insisting he “must do better” after registering his lowest championship finish as a Ferrari driver.

Vettel, who is now six years without a drivers’ title, finished fifth in the standings behind team-mate Charles Leclerc, recording just one victory all season.

It marks the first time since 2014 that the German has been outscored by a team-mate over a season, with a series of high-profile errors overshadowing Vettel’s fifth year at the Italian team.

When asked to give a personal assessment on his performances in 2019, Vettel said, as quoted by Motorsport.com: “We didn’t have the year that we were hoping for – full stop”.

“I think the reasons are clear, the lessons are clear, now it’s up to us to make sure to take them on board,” he continued to Sky Sports F1.

“As a team we must perform stronger, as an individual I think I can. I must do better. I can do better – it wasn’t a great year from my side”.

Despite his critical judgement of his campaign, Vettel stressed: “I don’t think it was as bad as it looks.

“There were many small things probably leading to maybe not a great picture in the end. But still, I’m the first one to look at myself and if I’m honest, I know that I can do better.

“That’s for sure the target for next year – to do a step forward. And hopefully we get a stronger package as well to fight with Mercedes and Red Bull in the front.”

Intense speculation during the year suggested the four-time world champion was considering calling time on his Formula 1 career after Abu Dhabi.

Responding to the rumours, Vettel joked, as quoted by Crash.net: “I was already doing holiday next year, I heard before I’m stopping.”
