FIA president Jean Todt is unhappy at those who he claims stir "negativity" and "controversy" in Formula 1.

Right now is a key point for the future direction of the sport as Liberty Media look to implement an overhaul of the sporting and commercial regulation as part of a new Concorde Agreement for 2021.

However, when any idea is proposed, the response is always very mixed with many of the same people often always making the case against change.

Explaining his point, Todt referred to the furore around the new aero designs introduced for this year.

"I've heard everything from it's a waste of money to it's a fantastic improvement in overtaking opportunities," he said at the Geneva Motorshow this week

"That's why I'm really excited about what the new rules will actually bring."

McLaren driver Carlos Sainz agreed, saying: "It seemed extremely negative and even disloyal to attack without giving it a chance. Why complain about your meal before you have tasted it?

"Even in the tests it is difficult to comment, but I was able to overtake a couple of cars, follow them, and I did not get a bad impression.

"How much better or worse is impossible to say now because it would be measured in tenths, but I got a fairly positive impression on a very bad circuit for overtaking.

"That could be the same in Melbourne, so we will have to wait three or four races to find out."

Returning to his broader unhappiness at how some approach F1, Todt continued: "Instead of being positive and working together to build the best motorsport product in the world, some just want to see the mistakes.

"That's a bit unfortunate."
