Red Bull motorsport boss Helmut Marko insisted once again that neither Daniel Ricciardo nor Max Verstappen will be racing with any other team than Red Bull next season.
Pundits still appear to spinning rumors of either driver leaving the Milton Keynes-based outfit, but Marko has stepped up once again to clear the matter once and for all.
"Ricciardo and Verstappen have fixed contracts, Ricciardo for 2018, and Verstappen with some clauses for even much longer," the Austria told Germany's Sport Bild.
Marko also confirmed that Carlos Sainz - another man frequently short-listed by rival teams - was also on a tight leash with the energy drinks company.
"That also applies to Carlos Sainz," said Marko.
"He is also bound to us in the longer team. Until 2019.
"Only we can end contracts -- the drivers cannot."
