Alonso: We expected that we were in for a difficult weekend.

      Aston Martin's drivers ended up outside the top ten after the conclusion of practice in Las Vegas, with Lance Stroll 11th and Fernando Alonso 18th.

      Fernando Alonso (18th): "We expected a difficult weekend — and it is indeed difficult. Our pace hasn't been very good so far, but we'll see what we can do in the preparations for tomorrow. Today's results are hard to interpret, especially since the end of the session was interrupted by red flags and nobody managed to complete a lap. We'll see if we can find a higher pace. There was a light shower at the start of the second practice, but the forecast doesn't promise rain for tomorrow, so we're not too worried. We'll see if we can get everything right."

      Lance Stroll (11th): "Of course there's work to do, but the feeling in the car isn't that bad — we'll see what tomorrow brings. On this track the result depends a lot on confidence under braking, and we've been trying to build that confidence up gradually. We needed to find that last metre to be able to brake as late as possible, but the track is very slippery and the weather is cool here — I think the main difficulties in Vegas are precisely that. But during the session I drove with increasing confidence, we made small setup changes, and that was positive, but we need to keep working to make further improvements."
