Romain Grosjean insists he isn't thinking about the possibility of an outing in Renault's R31 before the end of the season with his focus firmly on wrapping up the GP2 title.
Five victories so far this year have allowed the DAMS driver to establish a handy lead at the top of the standings heading to Spa this weekend, with continued speculation that he could be moving towards a return to F1.
Having driven for Renault in the latter half of 2009 following the departure of Nelson Piquet Jr, Grosjean was then dropped ahead of 2010 as the team brought in Vitaly Petrov as team-mate to Robert Kubica but then returned to the fold as test and reserve driver this season.
With team boss Eric Boullier having talked up Grosjean's chances of making a return to the F1 grid, speculation has suggested that Friday practice outings could be possible before the end of the season, but Grosjean insists he is only focused on trying to wrap up the GP2 crown before thinking about F1.
“It's quite funny to hear rumours; speculation will always be there in Formula 1,” he said. “At the moment, it's not something we're thinking about. First of all, there is business to finish in GP2 then, if the opportunity presents itself later in the season, we will see.”
Grosjean could secure the GP2 title this weekend in Spa if results go his way.
