Adrian Newey has scoffed at rumours that suggest he could switch to Renault.
The Red Bull technical boss, who is arguably the most famous Formula 1 designer of all time, told Auto Bild: "That will not happen."
No chance of Renault switch
Red Bull's Dr Helmut Marko agrees, saying Newey in fact wants to stay put for a longer term.
"It is no longer about the if, but only the how of the new contract," he said.
Renault, too, denies that rumours about signing up Newey are accurate.
Team boss Cyril Abiteboul told AS newspaper: "I deny it completely and don't know where it comes from. I think it's a misunderstanding. I think Adrian is extremely loyal to Red Bull, so I don't know where that information comes from."
