There were times last year when it would not have been a big surprise if Sebastian Vettel had decided that Formula 1 was no longer for him.
This was especially true after the Italian Grand Prix, when the critics were on his back. Many in the anti-Vettel camp were suggesting that his time was up after his Monza race had effectively ended with an unforced spin, after which he hit Lance Stroll, while team-mate Charles Leclerc became the darling of the tifosi with a sensational win.
But leading sportspeople like Vettel don't reach the top by throwing the towel in after dark days. In fact, they're often inspired to hit their peak form after some of their toughest moments. And that's exactly what happened with Vettel last year.
