Vettel has struggled since swapping Red Bull for Ferrari four years ago and his title challenge has once again fallen to pieces this campaign.
Lewis Hamilton is on the verge of wrapping up the double for Mercedes and he leads Vettel by 67 points in the standings heading into this weekend’s US Grand Prix.
According to Italian outlet La Gazzetta dello Sport, Vettel has a termination clause in his contract which allows Ferrari to release their man man in 2019.
That would be one year before his current deal is due to expire.
They add that Vettel feels “isolated” at Maranello as he is continuing to lose support from the hierarchy.
Italian media have recently slammed Vettel for his performances.
And the criticism has got that bad Hamilton has stepped in to ease some of the pressure on his rival.
“I feel the media need to show a little more respect for Sebastian,” Hamilton wrote on social media.
“You simply cannot imagine how hard it is to do what we do at our level, for any athlete at the top of their game that is.
“It is to be expected that being humans we will make mistakes but it is how we get through them that counts.”
However, Ferrari boss Maurizio Arrivabene has recently given his public backing to Vettel, but it is unclear if he will show the same faith if results do not improve within the next 12 months.
“I know that the situation looks impossible but our job sometimes is to challenge the impossible,” Arrivabene told Sky F1.
“This is what we’re going to try to do. “We win and we lose together.”
Vettel won the World Championship for four consecutive years between 2010 and 2013.
But he has struggled to replicate the form of old in the red of Ferrari.
