Lando Norris won the Sao Paulo Grand Prix on Sunday to extend his lead over his McLaren teammate Oscar Piastri in the drivers' title battle.

Mercedes teenager Kimi Antonelli finished second with Max Verstappen third after starting from the pitlane as Piastri came in fifth to fall 24 points behind Norris with three races and a sprint to go.

"I was pushing, amazing race, a perfect weekend," said Norris who also won the sprint race 24 hours earlier.

Norris has hit a rich vein of form at just the right time, having won last time out in Mexico.

"Just focus on yourself, McLaren doing a great job, rewarding, it doesn't come easy that's for sure" said the Briton.
