Lotus Renault GP team boss Eric Boullier insists that Romain Grosjean is ready to make a return to F1 after wrapping up the 2011 GP2 title.

Grosjean secured the GP2 crown with a round to go following the Spa race weekend and will bring the curtain down on his championship winning campaign in the final rounds of the season this weekend at Monza.

The Frenchman will then switch his focus to trying to find a route back into F1 having previously contested seven races with Renault back in 2009 when he was called into the team to replace Nelson Piquet Jr.

Grosjean had been linked with a return to a race seat this season when it became apparent that Nick Heidfeld was to leave Renault, although the team has confirmed that it intends to field Bruno Senna for the remainder of the campaign now agreement has been reached with Heidfeld to release him from his contract.

However, Boullier - also linked to Grosjean through Gravity Sport Management - insists that the 25-year-old is now ready to return to the top flight after his difficult spell two years ago, where he failed to finish higher than 13th.

"He did it all in the correct manner which is very important," Boullier said of the manner in which Grosjean wrapped up the GP2 crown in Belgium. "Everyone is talking about him in the paddock now; he became the new GP2 Series champion three races before the end, which is impressive.

"He's done a good job in that discipline and I think he's now ready to step back into Formula 1."
