Carlos Sainz was "sad" and "angry" after yet another retirement cost the Toro Rosso driver the possibility of points in Brazil.
On a day where the Formula 1 grid seemed to have reliability in hand Sainz was the only retirement at the Interlagos circuit.
The Spaniard's STR10 broke down on the way to the grid and although the team managed to restart it in the pit lane, he "lost power" on the opening lap.
"It's the seventh time in the whole season," he said. "It means 50 per cent of the races that I have not finished.
"That is not what you want in a rookie year, and it's not what you are here for, you are here to get experience and to learn.
"So it's clearly not a good balance of retirements this season. But what can you do?"
And although he was "angry" and "sad" on the day, the rookie says he'll bounce back in Abu Dhabi.
"You are obviously sad for one day," he added.
"On Sundays I am very pissed off and angry with the situation because I think we had a great opportunity to score points again.
"It just didn't happen and today I'm sad, angry with the situation but tomorrow I will be completely fine and looking forward to Abu Dhabi."
