Piastri and Webber end manager partnership after Brazil

Oscar Piastri and Mark Webber announced jointly after the Brazilian Grand Prix that Webber and Ann Neal would no longer manage the McLaren driver. The timing was earlier than the end of the season, although the split had been signalled for some time. In pre-season testing in Bahrain, Piastri said there had been no specific trigger, only a decision to change the arrangement, with Webber still involved but no longer as present at races.

The 2025 season was intense, including behind the scenes, and McLaren's papaya rules, designed to treat both drivers fairly, created difficulties for the team at certain moments. Webber was reportedly not always happy with how McLaren handled some on-track situations or with the explanation for Piastri's form dip late in the year, which cost him the world title. Former Red Bull team principal Christian Horner has described Webber as a driver who motivated himself through adversity.
