Ralf Schumacher has reignited his spat with Haas boss Guenther Steiner by asking him to buy cosmetic cream, as the fallout over nephew Mick's exit continues.
Schumacher endured a difficult season in 2022 with Steiner publicly criticising the German after a series of crashes, before opting to replace him with Nico Hulkenberg.
The latest episode of Netflix's Drive to Survive delves into the relationship and also shows team principal Steiner considering replacing the German from a very early point in the season.
Ralf Schumacher has been particularly critical of the treatment of his nephew and in November, was accused by Steiner of trying to drag Haas into a 'public fight'.
And while he admits Schumacher did make mistakes, Ralf has again recently pointed the finger at Steiner. “I just have to say that I expect a grown man to treat a young man differently. I think the young man could have been motivated better," he told Formel1.de.
"In a team where you have the feeling that you are not wanted and you are actually going up against the sack, Mick has done a great job."
Now the brother of F1 legend Mick has poked fun at Steiner further, by asking him to buy his 'anti-wrinkle' face cream in an Instagram post he has since deleted.
In the post, Schumacher wrote: "With wrinkles and dry skin, I can only recommend Gunther my new cosmetic. At least you can still do something."
Schumacher has since joined Mercedes as a reserve driver, with Steiner claiming it was difficult working with Mick, and a fresh start was needed for all parties.
“Dealing with a Schumacher is not easy, as you can imagine. He was grown up about it. He wasn’t happy. I would say he saw the writing on the wall," the Haas boss said.
"He is a clever kid. He had two years. We didn’t get where we wanted to and I had to make some changes. You cannot beat up a dead horse.
“I just sat down with him and explained that we needed to bring the team forward with an experienced driver. It is part of the job. It is not a nice thing to do. I don’t enjoy it but you just have to be professional about it."
