Mercedes driver Lewis Hamilton, of Britain, celebrates winning his fifth Formula One drivers' championship during the Mexico Formula One Grand Prix auto race at the Hermanos Rodriguez racetrack in Mexico City, Sunday, Oct. 28, 2018.
He had been all smiles on Saturday after pipping Verstappen to pole position but made a poor start on Sunday with wheelspin dropping him to third. Even if there are a lot of things written, I really don't care. "Helpless I think is the best word". That's as good as I could get.
Asked how he meant to celebrate his triumph, Hamilton replied: "It is going to sound really boring, but I just feel content and really happy, so I am looking forward to going to sleep".
But the German could only manage second place, meaning Hamilton's fourth-place finish was inconsequential in his bid to retain the crown.

"I'm just praying for a smooth and safe race".
