1997 Formula 1 champion Jacques Villeneuve branded Oscar Piastri's Azerbaijan Grand Prix lock-up as a "rookie mistake".

The Australian driver suffered a double lock-up during the race at the Baku City Circuit while he was running third. Defending from Red Bull's Isack Hadjar down the main straight, Piastri locked the brakes and went wide into the run-off area. The incident took him out of podium contention and left him fighting in 15th place.

Piastri ultimately finished the race in 14th, and his team-mate Lando Norris crashed out after contact with the Alpine drivers, Franco Colapinto and Pierre Gasly.

"It was a rookie mistake," Villeneuve said while analysing the moment during the Sky Sports F1 broadcast. "He got caught out, looking in his mirrors, and just completely missed.

"It's the truth. Mistakes happen. You push too hard, but then you can see he was looking in his mirrors and just completely missed."

Three-time W Series champion Jamie Chadwick, who joined Villeneuve on the broadcast, shared her view of McLaren's race. "I had his radio on before," Chadwick explained of Piastri. "There was a lot of complaining generally from both McLaren drivers about struggling to get the best out of their car. Lando gets coached quite a lot throughout the lap in terms of where he can improve, where he can find performance."

She added: "At the end of the day, you draw a line, and it's a mistake. Even Oscar Piastri needs to look at it, but it's rare that you see a double lock-up like that from a driver like that. It seemed odd to me, though."
