Paul Hembery: "Qualifying got off to a tricky start as the drivers were immediately confronted with wet conditions for the first time all weekend in Q1, making it difficult to judge the amount of grip available - particularly as some parts of the circuit were much wetter than others. Generally we saw that the track got a lot quicker as each session went on, making the timing of each qualifying run absolutely crucial.
"As usual track position will be the key to a good result here tomorrow, but there is always scope to use a creative strategy to move further up the order. However, if the uncertain conditions continue tomorrow then the strategies will be blown wide open. We're still expecting to see more track evolution over the course of the weekend. Whether or not the drivers opt for one or two stops will depend on the speed of their cars and the track position they can maintain; we're not expecting wear or degradation to be a significant issue. Congratulations to Mercedes for a one-two on the grid; it will be interesting to see what they do with their strategies as they aim to convert this result into a race win."
