Williams' Bottas has a positive day in Monte Carlo

Rob Smedley, Head of Performance Engineering: There are some new parts we are running this weekend and we gathered lots of data in FP1. The rain affected our running this afternoon, so we couldn't complete our full programme, however we managed to use the option tyre at the end of the second session which was constructive. There is a lot to do to be ready for Saturday and Sunday, but we have an additional day in between which is positive to work through the data that we could attain despite the limited running.

Valtteri Bottas: It's great to be here in Monaco and good fun with the current cars. There are still some improvements we can make to be quicker and the rain didn't help in the afternoon, but we do have some good data to work from. Saturday will be vital in the morning for set-up and of course qualifying around Monaco is key to having a good weekend. Overall I am feeling positive and I'm looking forward to getting back in the car.

Felipe Massa: (FP1: 1:20.517, 16th / FP2: 1:20.394, 16th): Today was a tough day. I had some issues this morning with the power unit sensor so that limited my running, or at least the amount I could push. This afternoon it was wet and so I only went out at the end of the session and then suffered with traffic. The car is quick and Valtteri has shown that, so qualifying on Saturday will be very important.
