Pedro de la Rosa has urged his Sauber team to improve its reliability after his retirement from the Monaco Grand Prix.
The Spanish driver has failed to finish in five of the six races so far because of mechanical failures, with teammate Kamui Kobayashi also going out of today's race. The Japanese has also finished just once this year.
"When you look at the standings, it's zero points. We have to improve," de la Rosa told Spanish television. "Reliability is our Achilles heel at the moment. That's why before of every race I say we have to finish, we have to finish, because it doesn't matter how fast or slow you are if you don't finish."
De la Rosa, who retired with a hydraulic failure, said he is staying positive despite the problems, as he reckons there are good races coming up.
"We had a problem with the hydraulic system. I was going well but then I began having problems to change gears, then I lost the power steering and then I couldn't change gears anymore and I had to retire.
"What can I say? I wanted to finish here. We were doing a good job, the car was going well. Now we have to look to Turkey and keep a smile on your face before there are some very good races coming."
