The Mirror's senior F1 reporter, Daniel Moxon, has argued Norris’ friendship with the champion could hinder him as a competitor.
“Lando Norris insists he and Max Verstappen remain good mates despite their clash in Austria,” Moxon wrote in his column.
“Norris has been piling the pressure on his rival for a couple of months now and it was inevitable that they would clash at some point - Verstappen has a track record.
“It's got everyone in the paddock debating whether or not it's possible to be friends with your championship rival. Whatever is the answer to that, what Norris can't afford to do is see his Red Bull rival as a mate after he pulls down his visor.
“Even with Red Bull not as dominant as they were, the Dutchman continues to do the business and you have to be perfect to beat him. Norris has learned that in recent weeks - small mistakes cost him in Canada and Spain.
“Going up against Verstappen is the biggest test of the Briton's title credentials and he'll fail it if he can't see that the Red Bull racer is his enemy, not his friend, in the F1 world.”
Norris appeared to be back in contention for the win at Silverstone last weekend but conceded to Verstappen with the rivals finishing P2 and P3 behind the Mercedes of Lewis Hamilton.
The two will battle it out on track yet again at the Hungarian Grand Prix on July 21.
