Bernie Ecclestone says he would have no complaints if some teams were forced out of F1 especially if they "cannot afford it."
In recent months concerns have been raised about the financial viability of some of the Formula 1 teams.
The latest speculation related to Caterham while Sauber, who have yet to score a point this season, have also been dogged by rumours.
However, should either team, or any other for that matter, fall away, Ecclestone says he will have no issue with it.
Asked if he was worried about the grid shrinking, he told Autosport: "In fact, I would be happy.
"It's like a poker game. You don't know the other players. They should not be in the game.
"You should not be in this business if you cannot afford it."
The F1 supremo also weighed in on the sport's regulations after the stewards took a tough approach on any driver crossing the line at Turn 8 during qualifying for the Austrian GP.
"We have too many rules that are not necessary.
"When a driver crosses a white line he will be punished. That's wrong.
"Drivers are racers and they want to go racing, so let them do so.
"The stewards should be locked in their room [during the race] and take a look into any infringements after the race, not during the competition."
