Lando Norris uncertain McLaren can fix 'painful' straight-line speed issue ahead of Singapore Grand Prix

Lando Norris has admitted uncertainty over whether McLaren can resolve a straight-line speed issue ahead of the Singapore Grand Prix, a problem that hampered him in both Azerbaijan and Malaysia. The reigning world champion had been in strong form earlier in the season, claiming three pole positions and two victories in four races around the summer break. The Singapore Grand Prix will feature F1's first ever Sprint weekend, with Sprint Qualifying scheduled for 1pm on Friday.
