Carlos Sainz: "I think it was a positive FP1 this morning. The car was well-balanced and quick straight away. During this afternoon's session we had a bit more of a problem, especially with traffic management, and when I went to do my Option run I wasn't able to put a lap together as I didn't find any clear space. But we've seen that with some clean running like the other car had, we managed to do a good lap time, so I'm calm and positive about where we are."
