Trulli hopes to turn tables on H-HF

"I hope things are going to change," said Trulli, who qualified seventh in Sao Paulo, one place ahead of Frentzen. "In the past during the races I have always been ahead of Heinz-Harald Frentzen and in a good position, but so far I have just not got it completely right.

"In Melbourne, the engine failed, and in Malaysia it was a very unusual situation. When it was raining very hard, I started aquaplaning because I was on dry tyres and was trying to get back to the pits.

"Probably for the first time in my life, I wished I was not leading the race. I then went out."

Trulli bemoaned the fact that his practice and qualifying form has not translated to a good race result this year.

"I am always performing well on Friday. I seem to do well in qualifying generally and hopefully one day I will do well on Sunday - perhaps this weekend," he said. "It would be nice to be in front of Heinz."

He added: "Luck has not been on my side. I hope this period will end soon. You need luck to be successful."
