Three-time Formula 1 world champion and non-executive chairman of the Mercedes team Niki Lauda has fired a warning shot at the sport's owners Liberty Media.
The 68-year-old Austrian has questioned the future direction of the sport as Liberty Media looks to bring in new rules that will level the playing field and make Formula 1 more focused on entertainment.
The American company announced cost-cutting measures and an engine proposal for the sport from 2021.
That view, while resonating with many sports fans, has angered leading team Ferrari, who threatened to walk away from the sport earlier in the week.
Now the outspoken Lauda has backed the views of his team's biggest rival.
