But the German would not allow his disappointment to turn to bitterness, giving credit to Hamilton for his latest F1 triumph.

"It's disappointing, but it's not important what we've done today," Vettel told Sky Sports . "It's more important what Lewis has done.

"He's done a superb job all year round, so congratulations to him. It's not about anybody else, today is about him. It's his day."

Despite acknowledging Hamilton's achievements, the 30-year-old insisted he would back himself to continue competing with the world champion, who became the outright most successful British driver of all time.

"I don't fear him - I like racing with him," Vettel added. "Obviously I would have liked that a bit more this year, but they were the better bunch."

Asked what Ferrari could have done differently, he simply replied: "What does it matter now?"
