Mercedes has elaborated on the thought process behind the strategy call which left Lewis Hamilton berating the pit-wall during his remarkable Monaco Grand Prix victory drive.
Hamilton spent much of the race questioning his team's strategy after an early pit-stop on lap 11, forced on the leaders by an early Safety Car period. His car was fitted with the medium tyre to go to the end of the race instead of the more durable hard tyre.
The reigning world champion was concerned his tyres would not make the finish.
