Nico Hulkenberg believes that a loss of power in his Force India cost him a couple of positions during qualifying for the Italian Grand Prix.
Hulkenberg, who was unable to start in Belgium due to a power problem, crawled to a halt in Q3, having set a time good enough for ninth on the grid.
"It’s good to be in the top 10, but without the problems in Q3 there was the potential to be much higher up the grid," he said.
"I just lost power on my in-lap following my first run on used tyres, which was caused by a problem with the fuel system. I made it back to the pits, but the mechanics had to push me back to the garage and we lost a lot of time.
"When we tried to restart the car, the gearbox was stuck in between two gears and I couldn’t select neutral in time to get out again for a lap on new Soft [tyres].
"It’s a shame because I think sixth or seventh place was possible today. I’m sure we will fix these issues for tomorrow, but grid position is important here so it’s going to be a bit more difficult starting from ninth."
Force India team-mate Sergio Perez will start from seventh position.
"In Q3 I was a bit too optimistic and tried to get a tow from Kimi [Raikkonen] on the straight but it didn't work: it actually cost me a couple of tenths but in any case it wouldn't have been enough to be in front of the two Williams cars," said Perez.
"The race will be hard, but our target should be to challenge Williams ahead of us."
