Lewis Hamilton had a suggestion for a Sebastian Vettel fan who claimed the German was better than him during a live Instagram session.
Hamilton left Singapour in an ebullient mood after his crushing win at Marina Bay, and flew straight back to Vienna early Monday morning along with Mercedes' bosses Toro Wolff and Niki Lauda, and on board the latter's private jet.
While waiting to get clearance for take-off, the championship leader indulged in a live Instagram session with his 4.8 million followers.
During the live post, a Ferrari and Vettel devotee suggested his favourite driver was better and more accomplished than Hamilton. An assertion which the three-time world champion answered with a jibe of his own.
"One day you will see that that's not the case," said Ham.
"If you haven't, then maybe you need to go to Specsavers."
Enough said.
