Guenther Steiner says there’s only one possible explanation for Oscar Piastri’s poor 2026 form

Oscar Piastri's performance in the 2026 Formula 1 season has significantly declined, with him now trailing teammate Lando Norris by 55 points after previously leading by 34 points. Guenther Steiner attributes this drop in form to the reduced role of Mark Webber in Piastri's setup, suggesting that Webber's presence was crucial to Piastri's success last season when their head-to-head results were level.

Steiner noted that while other elite drivers have adapted to changes in regulations, Piastri has struggled, possibly due to the absence of Webber at the track. Piastri has since reshuffled his management, which has led to speculation about the impact of this change on his performance. Despite these challenges, Piastri continues to build his experience, having recently completed his 80th race.
