George Russell and Sergio Perez both had their races ruined after a collision at the Austrian Grand Prix.
When a Mercedes and a Red Bull go up against one another, we are used to seeing Lewis Hamilton and Max Verstappen engaged in battle. But this time it was their team-mates, as they fought for fourth place on the opening lap of the race.
Russell had track position and was trying to defend against Perez, who tried a move around the outside. For a moment it looked like both drivers left a fair amount of room, but the Mercedes understeered coming out of the corner and they touched wheels.
