Former Formula 1 driver Romain Grosjean was left puzzled by Oscar Piastri's performance at the end of the 2025 season, claiming it "felt like it was his cousin driving".
The McLaren driver had a strong start to the year, securing 12 grand prix podium finishes ahead of the summer break, six of which were victories. But after the summer break, he won the Dutch Grand Prix and finished third in Italy before going six grands prix without a podium.
