Jul.27 (Inautonews.com/GMM) Three formula one teams are interested in signing Romain Grosjean, according to Renault chief Eric Boullier.

Frenchman Boullier, who also heads the Gravity driver management company, is reportedly considering his countryman as an immediate replacement for Nick Heidfeld.

But L’Equipe quotes Boullier as saying “three teams” are in the running to have the 25-year-old – who is leading the current GP2 championship – in their 2012 lineups.

And Renault team owner Gerard Lopez admits Grosjean is a candidate to replace Heidfeld in 2012.

“Vitaly (Petrov) has a contract to the end of 2012,” he said. “We could consider Vitaly with Romain, but that doesn’t depend on us. It depends on the health of Robert (Kubica).”

Boullier admits Grosjean struggled in 2009 when he made his F1 debut amid the ‘crashgate’ scandal alongside Fernando Alonso.

“As I am very close to him, I can confirm that he is different now, much more mature than two years ago,” he said.

He told Globo Esporte: “We’re waiting to see what happens with Robert.”
