(Reuters) -Formula One champion Max Verstappen showed in Brazil last year, winning from 17th on the grid, that he can never be counted out but McLaren's Lando Norris and Oscar Piastri need no reminding of that in Sao Paulo this weekend.

The battle at the top between Norris and Piastri is on a knife-edge with four rounds remaining, with the Briton a point clear of the Australian.
