Binotto tendered his resignation from Ferrari at the end of 2022, after a series of strategy errors in that season cost the team the chance to challenge Red Bull for the world championship. He was replaced by Fred Vasseur.
The identities of Audi's driver line-up have long been the subject of speculation, with new regulations likely to lead to a shake-up on the grid.
"Regarding the current level of engine engineers, Audi seems to be struggling more than their rivals," reported formu1a.uno.
"Some sources continue to report they are finding it difficult to acquire the best engineering minds.
"Mattia Binotto is undoubtedly one of Audi's targets to fill this role. However, the former Ferrari team principal would also have several other options.
"Despite some uncertainties and the arrival of a new CEO, Gernot Doellner, the German company has no intention of giving up its entry. They intend to complete the acquisition of the Swiss company founded by Peter Sauber."
