With the appointment of Stefano Domenicali as the new boss of Liberty Media, all the top people in Formula 1 have a Ferrari background.

Nevertheless, competitors Mercedes and Red Bull Racing are pleased to welcome the Italian on Friday.

"I'm not worried at all, Stefano is a man of great integrity," Mercedes team principal Toto Wolff told

Sky Sports on

Friday

.

In addition to Domenicali - who will succeed the American Chase Carey from 1 January - Formula 1 is driven by Jean Todt (FIA chairman) and Ross Brown (Formula 1 technical director).

All three of them worked at Ferrari in the past.

"I'm sure Stefano will develop the sport in the best possible way. That of course includes doing his best to slow us down in every possible way, but that's part of it," Wolff said with a laugh.

Wolff himself was also associated with the position.

Mercedes has been dominant in Formula 1 since 2014, while Ferrari has slipped a lot this year in particular.

Wolffs Red Bull colleague Christian Horner is also not worried with three former Ferrari people at the top of the sport.

"I think it's great that Stefano gets the job. He's

one of the good guys

," Horner said at a press conference in Sochi on Friday prior to the Russian Grand Prix.

"I took on Stefano for years when he was still team principal at Ferrari. He has integrity, was a real racer himself and knows the business well."

"I'm sure Stefano will be very strict with his impartiality in his new role," said Horner.

"I don't think there is any particular fondness of any of the three individuals in the Formula 1 top."
