Speculation arose last week that Vettel, 31, is considering retiring at the end of the year.
The German, who won four world titles with Red Bull, has been unable to end Ferrari’s 12-year Championship drought since joining the Italian side in 2015.
It was thought Ferrari may take a different direction and Fernando Alonso was linked with a return to the team yesterday.
But Italian F1 expert Leo Turrini believes the Prancing Horse are happy with their current driver line-up.
“At the moment nobody at Ferrari wants to see Vettel leave,” Turrini told Italian newspaper Qoutidiano.
“In Maranello, they are well aware that Captain America could drive the car, but he would not be able to win the Championship.
“Certainly Vettel currently has a feeling of legitimate frustration.
“He is in fifth year in Italy, he has given so much, he has made some mistakes, he has won a dozen Grands Prix or so.”
Vettel and Charles Leclerc are struggling to compete with the Mercedes duo Lewis Hamilton and Valtteri Bottas.
And Vettel is still fighting to be the top driver in his team.
“I think it’s positive. We’re pushing each other,” Vettel said.
“But I think in fairness and keeping the respect, I don’t think I’ve had easy team-mates in the past.
“I don’t think Kimi [Raikkonen] is slow. Obviously they are different: different people first of all, different drivers, different style.
“I think it became apparent for good reasons that Charles is very talented and very fast.
“So I think that’s a good situation for the team to have two drivers pushing the car to the limit and exploring the limitations, and trying to find out first of all what they are, and second how we can fix them.”
