Red Bull Racing boss Christian Horner is confident all F1 teams, including Mercedes, will sign F1's new Concorde Agreement by next Wednesday's deadline.
The all-important document will bind the teams to F1 for several years from 2021, dictating the sport's commercial, financial and governance future.
However, on Friday, Mercedes boss Toto Wolff revealed that the German manufacturer was still at odds with several provisions included in the covenant, although Wolff would not reveal the sticking points.
The Austrian also alluded to Mercedes' grievances regarding how its contribution to the success of the sport is being under-valued relative to Ferrari which receives each year a hefty historical payment from F1 and also enjoys a veto power against the rules in specific circumstances.
Ferrari and McLaren on the other hand claim to be ready to put pen to paper on August 12 and commit to the new agreement.
And Horner is confident that all teams will eventually line up next week to seal a new Concorde deal.
"I think it’s only a matter of days away," Horner said. "I would envisage that all teams would be signing at some point."
Horner has been through previous Concorde negotiations, mainly during the reign of former F1 supremo Bernie Ecclestone, but admitted that "it's been a different experience this time to previously".
"I think the agreement is what it is," he said. "The contents of it is confidential between the teams and the promoter.
"You have to look at the bigger picture and look at it as a partnership, in many respects, that we need Liberty to bring as much revenue into the sport and interest and coverage, that ultimately the teams and all participants will benefit from.
"You have to take a bit of a holistic view on these things, you’re never going to get everything you want. I’m sure it will be concluded in the coming days."
