Trulli frustrated by early retirement

Trulli was involved in the first corner accident when he went off when he tried to avoid making contact with Nico Rosberg.

The move sent Trulli off the track briefly before he returned to the Tarmac and was hit by the Force India of Adrian Sutil.

"It was a very frustrating day for me because I was optimistic our strategy was good and I would be able to score a lot of points," said Trulli. "Unfortunately my race did not last very long.

"I had a poor start because the engine didn't pull exactly as it should have done so I lost some positions and was right behind (Fernando) Alonso and (Nico) Rosberg going into the first corner.

"Rosberg went off then during the next corner he came back on to the track right next to me. I had to avoid him because he came back on really quickly.

"I had to steer off the track and lost control of the car over the grass, so I spun and someone hit me. But there is no point in looking back; now we have to focus on the next race when hopefully we can achieve a much better result."

Team-mate Timo Glock also had problems at the start but was lucky to avoid the accident.

The German, however, went on to finish in a disappointing tenth position.

"I had a tough race. At the start the car didn't pull away; I don't know why but we have to analyse it because Jarno didn't have a great start either," said Glock. "He was in front of me into turn one and then I saw him spinning.

"I got through the incident but then I was behind Nico and I couldn't get close enough to him in the slipstream; every time I was close my tyres started to go off. Even when I was in clear air today the car was not perfect so we have to look at what happened and try to come back stronger for the next races."
