Russell told his F1 reputation has suffered a devastating blow in 2026

The Briton finds himself in a difficult position despite Mercedes securing the Constructors' Championship at the Brazilian Grand Prix. While Antonelli celebrated his maiden world title in Mexico, Russell remains 128 points behind the Italian with three rounds remaining.

Russell's frustrations were evident during qualifying at Interlagos, where he criticised Mercedes over the radio after being instructed to back off on a lap he believed could have secured pole position ahead of Lando Norris.

Speaking on F1TV, 1997 world champion Villeneuve suggested that the outburst reflected a much deeper problem for Russell, whose status within Mercedes has changed considerably since Antonelli's arrival.

"It's because of the way the season went, the fact that he's lost the championship to his teammate in a brutal way," Villeneuve explained.

Russell joined Mercedes in 2022 and managed to outperform seven-time world champion Lewis Hamilton in two of their three seasons together. His performances established him as a potential future championship contender, particularly following Hamilton's departure to Ferrari.

However, Antonelli has emerged as Mercedes' leading driver in 2026, winning nine Grands Prix and securing 16 podium finishes on his way to becoming world champion in only his second season.

According to Villeneuve, the Italian's success has also affected Russell's position within the team, especially given Toto Wolff's close involvement in Antonelli's development: "He's realised he's not the love child of the team anymore. Antonelli is Toto's project. He's been put on the side a little bit, and his value in the paddock has gone down big time."

The Canadian believes Russell is increasingly aware of the situation and must respond if he wants to re-establish himself as Mercedes' leading championship contender.

Beyond his internal battle with Antonelli, Russell is also under pressure to secure second place in the Drivers' Championship, with Max Verstappen emerging as a major obstacle.

The Dutchman continued his impressive run of podium finishes in Brazil, recovering from 21st on the grid to finish second behind Norris. That result extended his advantage over Russell to 17 points, despite the Mercedes driver finishing fourth at Interlagos.

Villeneuve believes failing to secure the runner-up position would represent a particularly disappointing outcome for Russell, considering the strength of the Mercedes package throughout the season.

Mercedes secured the Constructors' Championship in São Paulo with three races remaining, underlining its advantage over the competition. Antonelli has been responsible for nine of the team's 12 victories and contributed 390 of its 652 championship points.

Russell therefore faces a challenging conclusion to the campaign, with Verstappen ahead of him in the standings and Norris also involved in the fight for second place.

Villeneuve believes the final championship position could have a significant impact on how the Mercedes driver approaches the winter break: "He knows that, unless he finishes second, it's going to be a long winter."
