Nick Heidfeld said fourth place at the Japanese Grand Prix was possible, but the German was left lamenting a problem during his second pit stop.
"Today was not our lucky day," said the BMW Sauber driver after finishing in sixth position. I'm very disappointed with this result. Fourth place was within reach but several things went wrong today, especially at the second pit stop when the rear-right wheel nut got stuck. But certainly I don't want to complain.
"These things can happen and normally we have very good pit stops. That was when I lost a position to Kimi, and I rejoined the race just behind him. When the safety car came out I lost another position to Nico, who was lucky to refuel while the safety car was out."
Heidfeld's teammate Robert Kubica also felt luck had not been on his side over the weekend, the Pole coming home in ninth position.
"The entire weekend was unlucky for me," he said. "Yesterday I wasn't able to show my good pace due to the red and yellow flags. Today I was stuck in traffic a couple of times. Furthermore I lost much time at the beginning of the race with a heavy and understeering car.
"Once the car was lighter and I got into my rhythm I was quite quick. I was then very unlucky with my first pit stop, as after the stop both Kimi and Nick were in front of me. That cost me time. Also after the safety car period I was in traffic. I was stuck behind Jenson. I was quicker than him in the corners, but was not able to overtake as we were missing some top speed on the straights."
