Even if there transpires to be no room at the inn at Lotus Renault GP in F1 2012, Romain Grosjean may still find himself on the grand prix grid next year, with Eric Boullier revealing that 'three teams' are interested in securing the current GP2 Series pace-setter's services.

Grosjean made his F1 debut as a replacement for Nelsinho Piquet at Renault in the wake of the salacious 'Singapore-gate' race-fixing scandal midway through 2009, but going up alongside double world champion Fernando Alonso and in an uncompetitive car to-boot, he was always on something of a hiding-to-nothing, truth be told.

Released at the end of the campaign, the Swiss-born Frenchman turned to sportscars and later last year returned to GP2. Remaining in the F1 feeder category in 2011 with DAMS, he currently leads the title standings with three victories from the opening ten races, and Lotus Renault GP managing director Boullier - who also runs the Gravity Sport Management stable of which Grosjean is a member - reflects that the 25-year-old is now finally ready to make the graduation to the highest level.

The Frenchman is reportedly evaluating the former F3 Euroseries Champion and inaugural GP2 Asia Series Champion as a replacement for the underwhelming Nick Heidfeld this season - and it is speculated that he could join the Enstone-based outfit in 2012 should the injured Robert Kubica prove unable to return - but even if that is not possible, Boullier concedes that Grosjean is in demand with as many as 'three teams' already chasing his signature.

"As I am very close to him, I can confirm that he is different now, much more mature than two years ago," he is quoted as having said by French sports newspaper L'?quipe, adding in an interview with Brazilian publication Globo Esporte: "We're waiting to see what happens with Robert."

"Vitaly [Petrov] has a contract to the end of 2012," added Lotus Renault GP majority owner G?rard Lopez. "We could consider Vitaly with Romain, but that doesn't depend on us. It depends on the health of Robert."
