'A lot to work on' for Williams - Massa

Felipe Massa says Williams has "a lot to work on" after Friday practice for the Spanish Grand Prix.

While Williams is often slower on a Friday relative to its Saturday pace, both cars were outside the top ten in FP2. Massa admits the two practice sessions did not go as smoothly as hoped and leaves Williams with plenty to improve on ahead of qualifying.

“I think it was not a fantastic Friday for us, trying to understand the tyres, trying to understand the car," Massa said. "I also made a mistake on my best lap with the new soft tyres, I went completely off on the outside of the track and I couldn’t do my best lap which is the lap. After that you get minimum 0.5-0.6s slower, so I did it on my second lap.

"So not so happy for the Friday compared to Russia for example but there’s a lot to work on for tomorrow and a lot to work on trying to make the car more competitive.”

However, Massa still believes Williams can recover the deficit to the likes of Red Bull throughout the rest of the weekend.

“I expect to be competitive. I expect to be maybe in a position to fight with Red Bull. We know it is not easy to have a good car here on this track but we will try.”

Having had a spin at Turn 5 in FP1, Massa said the error was simply a case of pushing too hard at the time.

“It can happen sometimes. I was trying to understand the tyres, I was trying to understand the limit and everything so for sure a spin can happen. I’m not worried about that.”
