The runaway leader of the drivers’ championship needs to finish ninth or better in his Mercedes to take the title aged 20 years and 68 days, lowering the record held by Sebastian Vettel by more than three years.

Almost more remarkably, he will also succeed Italy's last champion Alberto Ascari, who won for Ferrari in 1953, after a gap of 73 years during which his country has become synonymous with Formula One.
