The Mercedes team principal was forced to intervene multiple times over the team radio after the teenager became increasingly frustrated with his teammate during the Canadian Grand Prix Sprint.
The teenager’s anger stemmed from an early battle between the pair, which he felt had cost him a chance to challenge for victory. This ultimately prompted an internal Mercedes discussion involving both drivers after the race.

Antonelli was left frustrated after an early battle with Russell
The incident occurred in the opening stages of the sprint, when Antonelli attempted to challenge Russell for the lead. The young Italian believed Russell’s defensive manoeuvre was overly aggressive and that he had been forced off the track to avoid a collision.
Expressing his frustration over the team radio, Antonelli described Russell’s defending as “very naughty” and made it clear that he was unhappy with how the battle had unfolded.
Wolff quickly attempted to defuse the situation, telling his driver: “Kimi, concentrate on driving, not moaning on the radio.”
However, Antonelli’s frustration did not subside. The 19-year-old continued to reference the incident throughout the race as he tried to catch up.
Wolff delivers stern warning over team radio
Antonelli eventually crossed the line in third place, having lost second position to the reigning world champion, Lando Norris, following his earlier clash with Russell.
Even after the Sprint had ended, Antonelli was still fixated on the clash. When race engineer Peter Bonnington informed him that the race had finished, Antonelli responded: “If we need to race like this, that’s good to know.”
This prompted Wolff to step onto the radio again.
“Kimi, this is the fourth time you’ve brought this up. We talk about this internally, not over the radio, OK?” Wolff replied.
The exchange immediately caught the attention of the broadcasters covering the race.
Sky Sports commentator David Croft remarked: “That’s stern. Kimi is still fuming, and I think Toto is angered by the reaction and what he saw on the track as well.”
Former F1 driver Martin Brundle agreed with this assessment.
“It’s interesting that the headmaster has had to step in there, isn’t it? Bono was trying to calm him down, too, but finally the boss came on the radio to say, ‘Stop this,'” said Brundle.
Update: Mercedes holds internal talks after the race
The disagreement did not end with the chequered flag. Mercedes deputy team principal Bradley Lord later revealed that Wolff had held a meeting with both drivers after the race to discuss the incident and set out expectations for the future.
According to Lord, Antonelli jokingly compared the discussion to being summoned to the headteacher’s office.
“There was a sit-down and a chat with Toto, as well as with the two drivers.”
They talked about how the sprint had gone and how they wanted to race each other in future. Kimi referred to it as being a little bit like being called to the ‘headteacher’s office.’
Lord stressed that the conversation was constructive, highlighting that both drivers wanted the freedom to race each other fairly while prioritising Mercedes’ interests.
“The message from the drivers was clear: trust us to race each other. That’s what you hired us to do, and we can do it.”
Wolff is no stranger to managing tensions between teammates
While the disagreement between Antonelli and Russell is relatively minor (for now), it is far from the first time that Toto Wolff has had to step in to manage tensions between Mercedes drivers.
He famously oversaw one of Formula 1’s most intense rivalries between team-mates when Lewis Hamilton and Nico Rosberg fought for world championships between 2014 and 2016.
Despite Mercedes’ dominance of the sport, the relationship between the two drivers deteriorated as the title battles intensified.
The beginning of hostilities
A defining moment came at the 2014 Belgian Grand Prix at Spa-Francorchamps. On the second lap, Rosberg attempted to overtake Hamilton through Les Combes, resulting in contact that punctured Hamilton’s tyre and ruined his race.
The incident sparked widespread criticism and prompted emergency meetings within Mercedes, with Wolff and the company’s then executive chairman, Niki Lauda, publicly expressing their frustration.
The Spa collision is widely regarded as the moment when the rivalry moved beyond a competitive sporting battle to become a deeply personal contest. From that point onward, Mercedes management regularly found itself mediating disputes between its two star drivers while attempting to protect the team’s interests.
Wolff has not forgotten the past
Although Antonelli and Russell are nowhere near that stage, Wolff’s swift intervention during the Canadian Sprint suggests that he remains highly sensitive to any signs of friction developing within the team.
His preference for resolving disagreements internally rather than via team radio reflects lessons learned from the Hamilton–Rosberg era, when public disputes often dominated championship campaigns.
With Mercedes once again fighting at the front, and both drivers capable of challenging for victories, Wolff will be hoping that the Canada incident remains an isolated flashpoint, rather than being the first chapter in a much larger intra-team battle.
Wolff accepts passion, but wants less radio drama
As Mercedes continues its strong start to the season, the team faces the challenge of managing two drivers who are constantly competing at the front of the field.
Lord noted that discussions were necessary because the stakes are now significantly higher.
“It was important to talk, important to address those incidents, and important to recognise what’s at stake this year. They are racing to win each race weekend so far, and potentially the championship if we can maintain this level of performance throughout the season.”
Mercedes drivers must do better
Wolff later addressed Antonelli’s emotional radio messages, making it clear that, while passion is welcome, drivers must remain focused during races.
“No, I don’t think so. Obviously, when you listen to some of the radio communications, I think there’s room for improvement. But wearing your heart on your sleeve is fine; concentrating on the driving is important.”
The Mercedes boss added that he had no issue with the competitive spirit shown by either driver, but preferred disagreements to remain behind closed doors.
“That’s something we can clear up internally. But I don’t appreciate it so much — if that’s the right word — when emotions are elaborated on over the radio.”
With Antonelli and Russell increasingly fighting for victories, Mercedes may have had an early glimpse of the tensions that can arise when two championship contenders share the same garage.
