At the age of 37 and two years since his last grand prix, Pedro de la Rosa has not given up on one day returning to the formula one grid.

The Spaniard, who has not had a full time race Seat since 2002, today attends all the grands prix as McLaren's primary test and reserve driver.

He has been needed at the races by McLaren on a few occasions, most notably in 2006 following Juan Pablo Montoya's departure.

At Valencia, de la Rosa was put on standby while Lewis Hamilton struggled with the 'flu and neck pains, but ultimately the Briton took his usual place on the starting grid.

De la Rosa told sport.es that coming to the races simply to watch is a tough job.

"This year we have had two grands prix in Spain, so for me it is terrible," he said.

"I have to just think about the next test, the next time I will get into the car -- that's the only thing that motivates me," he explained.

"Also, Hamilton is doing a good job and I am happy about that because it means I must be doing my job well too.

"But it is only a consolation. Let me be very clear that my only aim is to be racing again, and as long as there is hope, I will continue to try," he said.

Pedro de la Rosa said any possible options for the 2009 season will become clearer within the next few months.

"Obviously I don't just come to the races to commentate for television or watch how my team is doing. I know it is very difficult, but I still have small hopes that I can be racing again."
