F1 bosses Chase Carey and Jean Todt are going along to the official launch in Italy.

Ferrari chairman Sergio Marchionne is set to hold a press conference at Alfa Romeo's Storico museum near Milan tomorrow to explain the reasoning behind bringing the famous Italian marque back to F1 at this moment.

The significance of the Alfa Romeo brand push in F1 has become clear though, with F1 chairman Chase Carey and FIA president Jean Todt both due to attend the event where Sauber's 2018 driver line-up may finally get confirmed.

The presence of Carey and Todt is especially intriguing because it comes against the backdrop of Marchionne having threatened last month to quit F1 after 2020 amid unhappiness about plans for new engine rules.

The Alfa Romeo deal with Sauber not only includes sponsorship and a likely full rebranding of the car in the company's red and white corporate colours. There will also be strategic, commercial and technological co-operation in development areas, which will include the sharing of Alfa Romeo's engineers and technical personnel.

Joining Marchionne at the press conference will be Sauber chairman Pascal Picci, who has been weighing up over recent weeks which driver to put in alongside Charles Leclerc. Marcus Ericsson has emerged as favourite to retain his seat there, having the backing of the team's Swedish financiers, while other candidate Antonio Giovinazzi could be handed a reserve or third driver role if he does not get a race seat.
