Rumours that Swiss team Sauber could become a junior platform for Ferrari are gaining strength.
New boss Frederic Vasseur's first task at Sauber was scrapping the planned 2018 engine deal with Honda, replacing it instead with a new arrangement to use the up-to-date Ferrari power unit next year.
At the same time, Ferrari president Sergio Marchionne is quoted by Italy's Autosprint as saying: "We have to find a place to lay the groundwork for tomorrow's Ferrari."
Earlier, Marchionne has spoken about setting up a satellite Ferrari team, perhaps to be branded as Alfa Romeo.
"It would be quite useful for Sauber to have someone like Leclerc as a driver," Speed Week quotes the Frenchman as saying.
Indeed, Monaco-born Leclerc impressed when testing the 2017 Ferrari in Hungary recently, and both the 19-year-old and Giovinazzi have subsequently been in action to help Pirelli with 2018 tyre testing in Barcelona.
