Sergey Sirotkin: "Both sessions were tough today"

Sergey Sirotkin finished 19th and 20th in the two sessions earlier today as the woes at Williams show no sign of ease. He sums the day up as "tough".

"Both sessions were quite tough today, as expected. I'm still quite calm because we're trying many things," he said in the Williams summary.

Despite the issues, the Russian remains positive for qualifying tomorrow. A bit of rain, which is forecast could act as a leveller and therefore increase their results potential.

"Once we looked into everything, the performance was better on the Saturday. I’m quite confident we can do that tomorrow. For now, it’s been a productive day and we just have to analyse everything."
