Sergio Perez has no chance of a fair title fight against Red Bull team-mate Max Verstappen, says former Formula 1 driver Romain Grosjean.
Verstappen is the runaway leader in the title race, 46 points clear of his nearest rival after just nine races as the winner of five of the last six. That second-placed contender is Perez, who emerged in the hunt to become champion after his Monaco Grand Prix success.
He is three points ahead of Charles Leclerc, who is still considered to be in the race for the title despite the reliability concerns that have affected his Ferrari in recent weeks. But Grosjean believes that the Mexican has no hope of challenging Verstappen due to team politics.
