Australia’s F1 2025 title hopeful has suffered an alarming slump in form over recent weekends, but having largely returned to the pace of McLaren teammate Lando Norris at Interlagos, Piastri declared that he “can definitely fight” with the McLaren package which he has underneath him this weekend.

Oscar Piastri risks reputational damage if he does not win this year's Formula 1 world championship, according to title rival Max Verstappen 's father, Jos Verstappen.

Oscar Piastri has seen a 34-point cushion at the top of the F1 world championship standings evaporate in five races.

Lando Norris beat McLaren teammate Oscar Piastri to the top spot in the sole practice session at the Sao Paulo Grand Prix, while title rival Max Verstappen toiled with setup problems en route to 17th.

McLaren team-mates Lando Norris and Oscar Piastri were quickest in free practice in Sao Paulo.

Max Verstappen, the only other driver in realistic title contention, 36 points behind Norris, was down in 17th place as his Red Bull team ran a different programme.
