Five things we learnt from Singapore GP

■

Vettel’s grumpy:

Sebastian Vettel was hardly a jovial figure when he arrived in Singapore, but he was incandescent after Ferrari’s weekend unravelled. “We didn’t come here expecting to lose 10 points,” the German fumed, after finishing a distant third.

The contrast between championship leader Hamilton’s body language and Vettel’s was plain to see all week. Hamilton was affable to all he encountered in the paddock. “I just feel, job done. I’m really happy with it,” he beamed as he spoke to reporters after the race.

Hamilton’s happy: Grosjean’s on a tightrope:

Romain Grosjean is walking a disciplinary tightrope, in danger of a one-race suspension from Formula One after ignoring blue flags in Singapor. Grosjean received a fivesecond race penalty and two points on his licence that took him to nine for ignoring the flags.

Esteban Ocon began the week by saying he couldn’t believe he might not drive in Formula One next year and ended it in despair as he was knocked into a wall on the very first lap. Ocon is due to be replaced by the new team owner’s son Lance Stroll.

Ocon’s going for a Stroll: F1’s got 2021 vision:

Ross Brawn, F1’s managing director of motorsports, was forced to confirm plans for futuristic Formula One concept cars for the 2021 season to improve racing after images were leaked — and the revelation immediately split opinion.
