Romain Grosjean has snubbed Jackie Stewart's offer to help him with his driving, saying right now it's not something he needs.
Earlier this week, Stewart said he'd be willing to help Grosjean with his driving as he reckons the Frenchman has the potential to succeed in F1.
"In tennis there are coaches and boxing, golf, skiing... everybody has one, but we don't," the triple World Champion told Autosport.
"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.
"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."
However, newlywed Grosjean says that while he's flattered by the offer, time constraints have meant he's had to say no thanks.
"He did offer, but the main issue is the schedule. It's very tight at the moment and I've a honeymoon to do," said the Lotus driver.
"Obviously, it's very nice to have comments like that from a triple World Champion. Let's see in the future. At the moment it's race after race, and the schedule is tight.
"You can always change. I used to work with a mental coach, but I don't feel I need one today.
"Maybe I'll feel different in the future. Things can change from week to week, but at the moment I'm happy with the way things are going."
