Timo Glock has said that Marussia can take the fight to Caterham at the Marina Bay Street Circuit.
Glock lamented a sensor problem that left him stranded in FP3, but was optimistic about the race.
"A disappointing start to the day in FP3 and then in terms of the knock-on effect this had on qualifying. To not have a proper run this morning cost us quite a bit, which is a shame as I had a good feeling in the car but not the confidence in terms of the tyres", he said.
" It was a bit of a struggle with the brakes also, which were not great", he said, at a circuit where the brakes play a big role.
"We had a good start yesterday and into the weekend, and we were actually looking quite strong. At least we were only a couple of tenths behind in qualifying and now we need to try and race Caterham hard tomorrow. In general the team did a good job with the challenges we faced and also the heat and humidity, which is a struggle. I hope we can do something better for them tomorrow"
Team mate Charles Pic received a penalty for overtaking under red flags in third practice.
"With regard to the penalty imposed by the FIA after FP3, I have seen the information and I would like to say that I completely agree with it. It was a mistake on my part and I will use the experience wisely", said the Frenchman
