Formula 1 is preparing for a crunch day of negotiations on the future of the sport in Geneva on Tuesday.

With the deadline of the 2017 rule changes rapidly approaching - it is set to be passed on 1st March but could be extended - it is hoped the talks between the influential stakeholders in F1 will be able to come to a decision on how they want to see the sport change next year.

The demand for faster racing and a more competitive grid has been a universal concern for all parties but the method of approaching the changes has caused friction and splits between teams as well as Bernie Ecclestone and FIA President Jean Todt.

With Ecclestone openly criticising F1 yesterday, claiming it is in its worst state ever and he wouldn't pay to attend a race, he clearly wants to push through rapid regulation changes while is also set to table his idea of a reserved top ten starting grid for 2016, but it is unlikely to receive strong backing.

Red Bull's Christian Horner has set his stall up by aiming for an aerodynamic regulations redraft by making cars up to five seconds a lap quicker but his proposal has been meet with scepticism by Mercedes boss Toto Wolff who feels Pirelli would need to make drastic tyre changes to bare the intensity and loads.

"When you look at the loads that would be triggered by these aero changes, they have never existed," Wolff said. "We would be excited about that if we were to achieve the car and tyres while still keeping the excitement in the sport and the overtaking capability.

"What we would like to achieve is a set of regulations that make the cars look aggressive, wider, bigger, more downforce, faster, but still within a feasible framework. Not just putting it on the car with the view that if the tyre manufacturer can't cope then we need to change the tyre manufacturer."

At Barcelona, Horner has tabled his counterargument and says Pirelli should not be used as a 'scapegoat' to alter any regulation plans.

Pirelli recently hosted a F1 stakeholder meeting at its Milan headquarters where these suggestions were submitted and has made it clear whatever regulations are decided upon it needs more tests and time to prepare to ensure it produces a safe tyre compound which suits the requirements.

"We had a very productive meeting with Pirelli several weeks ago where several teams and drivers went to Milan and Pirelli's HQ to go through any concerns," Horner explained. "It was made very, very clear to us at that meeting: 'Come up with the regulations and we'll make whatever tyres you want to suit those regulations."

"I think it's wrong to use Pirelli as a scapegoat to compromise regulations. I think F1 has to come up with a car that it feels it wants and it needs, and I'm sure that Pirelli can make the necessary product, as their chairman stated."

Also on the F1 agenda is decision on cockpit safety, a change to the race weekend format and engine regulations.
