Mercedes admits the decision to call Lewis Hamilton in for a tyre change at the final deployment of the Safety Car at the Brazilian Grand Prix was a "rookie mistake".
After Ferrari pair Charles Leclerc and Sebastian Vettel collided six laps from the finish a Safety Car was deployed to clear both cars from trackside and sweep debris away from the circuit. Hamilton was running second behind race leader Max Verstappen but made the surprising decision to come in for fresh tyres - the theory would have been to attack Max Verstappen for the lead, but there was no guarantee the race would be restarted and it meant sacrificing track position.
