Jaguar struggles to maximise potential

Unfortunately both drivers were disadvantaged after Heinz-Harald Frentzen dropped oil on the track before Webber's run. The session was stopped and the track brushed with cement dust but Mark had to abort his out lap and wait in the pits while the work was completed.

"It is impossible to say where I would have been had there been no oil, but either way, it's Saturday that we are now concentrating on," he said.

"The day started well this morning and I was able to complete a good programme with the team. We worked on rear mechanical set-up and of course qualifying set-up. The tyres are in good shape and I am pleased that we posted the fastest time this morning, particularly because I ended up having a slightly more challenging one-lap qualifying this afternoon."

Antonio Pizzonia is arguably still struggling to fulfill his potential when it matters most. The Brazilian went a second slower in the afternoon than in practice and expects to post a better result on Saturday.

"Slightly disappointed with 15th but the circuit was somewhat slippery," he said, "particularly just before the swimming pool corner. I had a lap that was one second faster this morning, so I know that the car is capable of more.

"My morning session however was good and we did what we had planned, despite me getting slightly too close to one of the guardrails at one point. Fortunately there was only marginal damage to the rim and we continued without problems. I am encouraged by the pace of the R4 on the track and I am looking forward to getting back on track on Saturday."
