Pedro de la Rosa insists that he is not searching for alternative employment for 2012, either in F1 or elsewhere, having returned to the McLaren fold this season.

The Spaniard has earned a reputation for being one of F1's best test and development drivers during a seven-year stint with the Woking team, but attempted to make a return as a race regular with Sauber in 2010, despite approaching his early 40s. That bid fizzled out after he was overshadowed by Kamui Kobayashi and, eventually, replaced by fellow veteran Nick Heidfeld but, after a brief stint where his development skills were utilised by Pirelli, he returned to McLaren for 2011.

Now, although his reunion was interrupted by a race run with Sauber in Canada, where rookie Sergio Perez was unfit to drive, de la Rosa insists that he will not be chasing a similar role anywhere else, content to play back-up to - and, if necessary, step in for - Jenson Button and Lewis Hamilton. That same dedication extends to offers from other championships, as the Spaniard insists that he has to remain focused on the job in hand.

"You can't have one foot here and one foot there," he insisted, "You would end up doing both categories at 80 per cent and run out of motivation and lose your contract.

"So, when people ask me if I would like to race as well, then of course I would, but is it the right thing to do? The answer is always the same, that I'm not willing to jeopardise my future in F1. Right now, it's the only thing that interests me, so I am quite proud to be here and I have no intention to change strategy in the coming years."
