His fourth Formula 1 world championship duly sealed in Mexico, Lewis Hamilton has come to the Brazilian Grand Prix determined to avoid the kind of dip in form he suffered after clinching his third title at the back end of the 2015 season, which helped Nico Rosberg win the final three races that year and set up his own championship charge the following season.
Hamilton has so far made good on his promise to "keep the pressure up exactly the same as it's been all year" this time around, having admitted his focus dropped after clinching the title in '15.
Hamilton was fastest of all in both Friday practice sessions for the 2017 Brazilian GP at Interlagos, suggesting he is still very much "in the zone" that has prevented the clinching of his fourth championship from properly sinking in yet.
