Fernando Alonso believes that Saturday will be better for his Ferrari team.
Alonso was only sixth in practice, 0.8s down on Sebastian Vettel.
"The day just ended was a Friday like any other, during which we got through everything on our programme. The morning session was dedicated to a comparison of various aerodynamic solutions, while in the afternoon, we concentrated on the tyres", he said.
"Between the first and second sessions, the track changed a lot, which to be honest was predictable, because there aren’t many races here over the weekend: at the start, it seemed very dirty but then it improved a lot and tomorrow, it will definitely be even better".
Felipe Massa also expressed confidence ahead of qualifying.
"We got through everything on our job list, which is always a good thing, both in the first and second free practice sessions. We tested the tyres in the usual way – first on a low fuel load and then with a lot more - to evaluate them over a long run", said the Brazilian.
"From what we could see, over a long run we are reasonably competitive, but less so on a single flying lap. Sure, it would be better if we were a bit quicker, but we will see what the situation is when it really matters, which means to say tomorrow afternoon in qualifying".
