Vettel wants one-year Ferrari extension
But Finland's Ilta Sanomat newspaper now cites sources in saying Ferrari and Vettel are in fact not in agreement over the duration of a new deal, with the German pushing for a mere one-year contract in order to leave his options open for 2019.
"It's true that I haven't got a contract yet," Vettel admitted, "but I think the primary objective at the moment is not worrying about papers but making sure we get good results."
Another rumour is that Vettel signed a pre-agreement with Mercedes prior to the 2018 season, whereby the 30-year-old would not agree a post-2017 deal until after July.
Vettel said: "As I've said, I'm not in a rush, I don't think the team (Ferrari) is in a rush, and as far as I understand I think I have a good contact with the team and they would tell me otherwise.
"So as I've said there's no problem -- nothing wrong."
