McLaren Formula 1 team principal Andrea Stella says Oscar Piastri's return to form in Qatar fits within his high-grip theory about the Australian.
Piastri struggled for pace compared to team-mate Lando Norris at low-grip circuits in Austin and Mexico, and also saw Norris beat him in Brazil and Las Vegas. But the Australian was back to his very best this weekend in Qatar, taking a clean sweep of sprint qualifying, the sprint race and pole for grand prix qualifying – his first since Zandvoort at the end of August.
