Romain Grosjean insists he is ready to return to Europe to replace the injured Robert Kubica.
The Swiss-born Frenchman, who along with Bruno Senna is a third driver at Renault this year, is currently in Abu Dhabi for the start of the GP2 Asia series.
But at Jerez, Senna is driving the R31 this week, as experienced drivers including Nick Heidfeld, Pedro de la Rosa and Vitantonio Liuzzi are considered for the injured Kubica's race seat in car number 9.
"I am ready to answer the call, but for now I'm here to race in GP2," Grosjean, who tallied an unremarkable 7 debut Grands Prix with Renault in mid 2009, is quoted by L'Equipe.
"My goal and (management company) Gravity's goal is for me to be in F1 in 2012, and we will work towards that step by step.
"If they do call me (for Kubica's seat), I'll go, but if they have something else in mind, I accept it as a member of the team.
"I will always support the team and, at the moment, all of my thoughts are with Robert," added 24-year-old Grosjean.
Another candidate reportedly discounted for Kubica's seat by team boss Boullier is Force India reserve driver Nico Hulkenberg.
"In my eyes, he is the best person available," former driver Jos Verstappen wrote in his latest column for De Telegraaf newspaper.
"I see the German with great potential; very fast, a hard worker and a winner in many classes of racing."
Speaking to reporters at Jerez on Thursday, however, Boullier said Hulkenberg is not a candidate because of his lack of experience.
