Mercedes team boss Toto Wolff said George Russell had "lots to learn" after the Mercedes junior driver clashed with Valtteri Bottas at the Emilia Romagna Grand Prix.
Russell, who is on a long-term development contract with Mercedes but currently drives for Williams, collided with Bottas while attempting to take ninth position from the Finn on lap 32 of the race.
The incident resulted in the two drivers crashing out of the grand prix and left them blaming each other for the extensive damage to both cars.
