Former F1 driver Johnny Herbert believes both Norris and Piastri must adopt a "selfish" mindset to win this year's F1 world championship.
Herbert noted a deliberate separation between the two drivers after the Silverstone race, suggesting Norris is maturing into a more ruthless competitor.
The next race is the Belgian Grand Prix at Spa-Francorchamps, where Piastri will be looking to rebound after a penalty cost him the win at Silverstone.
