Raikkonen did not even complete a lap

The McLaren driver suffered suspension failure and spun off in the first session of qualifying on Saturday.

"It's very disappointing to not even complete one timed lap," said the Finn.

"It is far from ideal to start from the back, but there are overtaking chances at this track and I've done this before and achieved good results."

Kimi will be frustrated because we all want to win world titles, and to do that, you need reliability Ron Dennis McLaren boss

McLaren boss Ron Dennis acknowledged that the team's continuing reliability problems could lead to Raikkonen leaving.

His chances of beating Fernando Alonso to the title last year were dashed by several car failures.

Asked if Raikkonen would be frustrated, Dennis said: "Yes, he will be because we all want to win world titles, and to do that, you need reliability. "Why would we not recognise that failing to give Kimi the equipment to do that will make him think about his future?"

McLaren have signed Alonso for 2007, so either Raikkonen or his team-mate Juan Pablo Montoya will have to leave the team.

Raikkonen brought out the red flags after his damaged suspension sent his rear wheel smashing into the rear ring, shearing it off, and leaving the rear right wheel trailing at an angle.

Raikkonen nursed his car back to the pits while the session was suspended, but there was not enough time for repairs.

Dennis said the car had suffered a rear suspension lower wishbone failure caused by a manufacturing fault.
