Ferrari-aligned team Haas will make a driver announcement for 2016, their debut season at the pinnacle of the sport.
It is expected that two men with Ferrari links will get the nod: Maranello's official reserve Esteban Gutierrez, and Romain Grosjean, who might then stand a chance of stepping into a scarlet car for 2017.
"I don't know," claimed Ferrari chief Maurizio Arrivabene. "Haas did not inform us of their plans.
"Obviously if they were to ask us we would be ready to help them, perhaps creating a partnership similar to the one between Red Bull and Toro Rosso," added Arrivabene.
