Cape Town - Haas boss Guenther Steiner is hoping Romain Grosjean can continue to channel his frustrations in the right way next season after overstepping the mark in 2017.

The Frenchman increasingly frequent moans over team radio were a staple of seemingly every race weekend over the course of the season, but Steiner felt that he had to step in at the United States Grand Prix. 

“In Austin he was getting too much," Steiner said. "I told him we could hear him, but if you keep talking then we cannot talk to you. 

"If you are on the radio all the time then how can we tell you what to do? So somebody had to stop him - and usually that is me." 

Steiner believes Grosjean has improved since Austin and allowed the team to give him feedback about the issues he is facing. 

He added: “It is less, but I didn’t do a proper study on it. I think he has calmed down and realised it doesn’t help. Not that it is good or bad, just that it doesn’t help. 

"So why get like this rather than working in a constructive way? 

“He still has his outbursts but normally they are shorter. Unlike Austin, when we had a bad day."

Steiner, though, conceded that the situation will never be fully resolved. 

"Even if I did study it I can’t fix it anyway,", he said. 

"We speak sometimes about it but not about fixing it. More about what he thinks it does to help.

"He has calmed down but still has he peaks. I will not change that.”
