Belgian GP: Williams qualifying quotes

Valtteri Bottas - 20th: "It was a disappointing qualifying because we had the ability to be higher but we were caught out by the changing track conditions. We went out on intermediate tyres earlier than others but the track was drying faster than we expected and by the end we could probably have got away with being on dry tyres. We were also struggling for overall grip on the intermediates and we were sliding quite a lot in the corners and this was losing us time. It's a shame as there was a good opportunity to do well today, but hopefully the weather will be like this tomorrow as it gives us the chance to look at different strategy options."

Xevi Pujolar, chief race engineer: "We knew qualifying would be wet and it started well with the track getting better throughout Q1. The end of the session would be where it was all decided and we brought both cars in for a new set of intermediate tyres. A few teams took the risk to change onto dry tyres, which worked for them, although the majority came in for intermediates as well. We were at the front of the queue so had time for more laps, but as the tyres were at their best on the first lap it meant that as the track improved we were unable to improve our times and unfortunately we did not progress beyond Q1. Overtaking is possible at Spa-Francorchamps and we have a good car for the race with a good top speed, so we can still make progress in the race tomorrow."
