“Over the years I’ve gotten used to dealing with criticism, even if it’s not fair,” the German told Sport Bild.
However, he says he is not giving up.
“I think it’s clear that I’m not in the spring of my career anymore,” said Vettel.
“On the other hand, at 31 I still have plenty of time in this sport. Looking back, Michael was even a bit older than me when he won his first title with Ferrari. And Lewis is two years older than me.
“I still have no thoughts of retiring,” Vettel added. “On the contrary, I’m doing everything to fulfil my dream of the title with Ferrari. And my family supports me.”
So, when asked if he has thought about switching to Mercedes, as his mentor Michael Schumacher eventually did, Vettel answered in the negative.
“No, my goal is to win with Ferrari,” the four-time champion said.
