Jackie Stewart offers Grosjean help to try and minimise on-track incidents

The Lotus driver has enjoyed an impressive return to grand prix racing, proving to be a good match for Kimi Raikkonen and having finished on the podium twice already.

The Frenchman, however, has seen chances of strong results vanish due to on-track incidents.

Three-time champion Stewart believes Grosjean could use some mentoring in order to improve his driving.

"I just said to Romain Grosjean the other day, it would be a good idea if you came up home one day for lunch so we could have a bit of chat," Stewart told AUTOSPORT. "It is ridiculous that in Formula 1 we don't have coaches.

"In tennis there are coaches and boxing, golf, skiing... everybody has one, but we don't. I am not looking to be a coach, but I know I can help him. Racing drivers historically have not been great listeners, but I think I might be able to help."

Stewart reckons the Williams team set a good example in hiring former GP driver Alex Wurz as a driver mentor for this season, when the Grove team is using two inexperienced drivers in Pastor Maldonado and Bruno Senna.

"That I think is a very good thing. Maldonado is very fast but he needs help. He shouldn't have the number of collisions he has had, and neither should Grosjean. That is not all bad luck, you're in the wrong place, alongside the wrong people.

"That is a trait they can change - categorically. Having said that, I am impressed with Romain's speed, and actually I think he will win a race this year. What they have got to do is not get into trouble, and not make poor starts."
