Toto Wolff has debunked rumours that Oscar Piastri is getting 'sabotaged' by McLaren after looking into the Australian's data.
Last weekend, Piastri lost further ground in the race to become the Formula 1 world champion after a poor Grand Prix in Brazil.
Having crashed out of the sprint race and then qualifying in fourth place, Piastri was already on the back foot as Lando Norris secured pole position.
On Sunday, Norris produced a brilliant performance to win ahead of Kimi Antonelli and Max Verstappen.

Meanwhile, Piastri's race was hampered after being handed a 10-second penalty for crashing into Antonelli, who in turn went into Charles Leclerc, ending the Ferrari star's race.
Over the last few weeks, Piastri has endured a drastic dip in form, having not won a race since August.
Due to the Australian's poor form, many fans have accused McLaren of 'sabotaging' Piastri and favouring Norris, which has since been debunked.
McLaren team boss, Andrea Stella, has previously stated that Piastri struggles when the grip is low.
In addition, Brazilian journalist Felipe Giaffone said Piastri ‘has to fine-tune this tyre management’.
However, looking at the data from the Brazilian Grand Prix, Mercedes team boss Wolff spoke about Piastri's tyre management, claiming he had kept the tyres in a 'perfect' window, which go against claims made by Stella and Giaffone.
The Austrian said: "The window is so small. Piastri was five or six tenths faster than both of ours at the end. That wasn’t the case before.
"You have to hit the window perfectly, and then you have performance. If you don’t, you don’t have it."
Speaking after the Brazilian Grand Prix, Piastri said: "I think in terms of the championship, there’s no point thinking about it very much.
"There are clearly some things we need to sort out. Just a tough weekend from a number of fronts, so I’ll focus on that instead."
The 2025 F1 season continues next weekend with the Las Vegas Grand Prix.
