Belgian Grand Prix: Williams Friday quotes

Bruno Senna - no time: "It wasn't too much of a useful day for the team, as we didn't have much running in the morning or the afternoon. We've done some good technical work trying to get the car ready for tomorrow and for the race. We didn't take any risk though as there was no need, but hopefully tomorrow will be dry and we can do some more laps to prepare for qualifying."

Valtteri Bottas - 8th: "It was very slippery out there today in difficult conditions. Visibility was poor when it was raining and when there were cars in front, but we still got a good amount of laps in and managed to do some practice starts from the pit box. I am continuing to learn and if it is going to rain anymore this weekend, the team have some useful data."

Mark Gillan, Chief Operations Engineer: "The poor weather completely dominated both of today's sessions with all the running being performed on the full wet tyre. Pastor felt that his balance in FP1, particularly at the start of the session was very good and his laptimes reflected this, being extremely competitive. Valtteri also did a good job in FP1. With conditions worsening in FP2 we only ran both Pastor and Bruno at the end of the session in order to optimise the car for the race starts. The weather looks much better for the weekend and there is a lot of work to do in FP3 ahead of both qualifying and the race."
