Brundle warns Russell: find 'overdrive' mode in 2027 or it's 'game over'

Martin Brundle believes George Russell must find an "overdrive" mode next season or face "game over" in his bid to win a championship with Mercedes, after Kimi Antonelli sealed the 2026 title with four rounds to spare in Mexico City.

Why it matters:

Russell started the year as the expected team leader, having comfortably out-performed Antonelli in 2025. Instead, the 20-year-old Italian has taken nine wins to Russell's three and become F1's youngest-ever world champion. For a driver who spent 2019-2021 waiting at Williams for his Mercedes chance — only to arrive as the team stopped winning — the reversal cuts deep.

The details:

• Brundle says watching Antonelli's rise has affected Russell: "George has had to observe that, and I think it's affected his own performance."
• Mexico City summed up the campaign — a lap-one deployment problem, a 10-second penalty for colliding with Isack Hadjar, and sixth place while his teammate celebrated the crown.
• The stopwatch is the real damage. Brundle argues Russell could not match Antonelli for consistent speed, "especially in the second half of stints in a run on a set of tyres."
• On Antonelli, Brundle sees "all the hallmarks of a multiple F1 champion," though he warns that carrying a title around the world brings a new level of pressure and expectation.

What's next:

Brundle expects the setback to provoke a response rather than end Russell's career, but the demand is blunt. "He has to come back next year and lift his game up. George has either got an overdrive or it's game over."
