Pedro de la Rosa has denied rumours Alex Wurz, his former McLaren test driver teammate, could be involved in the rescue of the dying Spanish team HRT.
Spain's AS newspaper said former F1 driver and Austrian Wurz, currently a 'driver coach' at Williams but also running his own company Firma Test and Technik, has been involved in talks to save HRT, whose lead driver is de la Rosa.
"No, it's not true," de la Rosa said.
"I believe Alex has already denied it, but I am sure he is here (at Interlagos) and you can see what he says."
De la Rosa, 41, acknowledged that Sunday's Brazilian grand prix could be his last grand prix.
And he warned others in pitlane about suffering HRT's fate.
"Apart from McLaren, Ferrari, Red Bull and maybe Mercedes, the future of all the other teams is not very secure," he is quoted as saying.
