Four time world champion Sebastian Vettel admits the upcoming Formula One season could be his last one in the sport.

Vettel will depart Ferrari at the end of the campaign with Carlos Sainz set to replace him at the Italian team for the 2021 campaign.

The 32-year-old has yet to agree a deal with another constructor, though McLaren have left the door open should Valeri Bottas or Lewis Hamilton not sign contract extensions.

“Obviously, I want to make sure I make the right decision for myself and my future. I think I have a very competitive nature, I have achieved a lot in the sport,” the German said ahead of the upcoming Austrian Grand Prix.

“I’m motivated and willing to achieve more. To do so I need the right package and the right people around me, so that’s what I’m looking out for at the moment.

“If the right opportunity should arise then it is quite clear. If that’s not the case then I’ll probably have to look out for something else.”

Vettel added that he won't rush into a decision on his next move:

“I am of the conviction that if you shut the door then you should not shut it in the expectation that it will open again.

“You have to be aware of the decision you are making, that’s also why I am not rushing into anything.”
