Senna handed over his car to Valtteri Bottas in first practice but managed eleventh in second practice.
"It was a tough day today. Tyre degradation was quite high and we had a few braking issues which made it difficult to read what the car was doing", said the Brazilian, who is racing with a new helmet design this weekend. "However, we have a lot of data from today to work through ahead of tomorrow. Qualifying in the top ten is possible, as we’ve seen the pace in Pastor’s car, so we’ll be working hard tonight to make further improvements tomorrow".
Pastor Maldonado was more cautious regarding their qualifying potential.
"Today was much better as everything came together and I am happy for that. Our long run pace looks quick again, qualifying pace less so but I think we are still looking good when compared to what everyone else was doing today. Qualifying will be important here as well as it’s difficult to overtake. I like this track though and we are looking competitive", he said.
