McLaren Formula 1 team boss Andrea Stella believes Lando Norris blocking Sergio Perez played a crucial part in Oscar Piastri's Azerbaijan Grand Prix victory.
Piastri was shadowing Ferrari's leader Charles Leclerc in the first stint of a one-stop race when third-placed Sergio Perez attempted to undercut the McLaren driver by being the first to pit on lap 14. Rather than responding immediately, Piastri stayed out for two additional laps before his lap 16 pitstop, which saw him in danger of losing second to the Red Bull.
