Christian Horner says that Sebastian Vettel put in one of the best drives of his career in Singapore – but he insists that it’s still too early for Red Bull to become overly confident about a fourth title.
“We’ve only extended the lead by another seven points,” said Horner. “Fernando keeps finishing the races, he keeps turning up on the podium. We’re 60 points ahead, we’ve extended our lead, but there are still 150 available. So we’ll keep our heads down and keep pushing.
