Ferrari signs new aero boss Bigois - report
Ferrari driver Fernando Alonso of Spain steers his car during the second practice session at the Monaco racetrack, in Monaco, Thursday, May 24, 2012.
That is the claim of the authoritative Italian publication Autosprint, who first reported the move as a rumour a month ago.
Autosprint's correspondent Alberto Antonini said Loic Bigois, a 52-year-old Frenchman, will now "definitely" move from Mercedes in mid-September, although an official announcement will probably not be made.
Bigois started his career with Ligier/Prost, moving to Minardi until 2003 when he was recruited by Williams as chief aerodynamicist.
In 2007, he moved to Honda, which became Brawn and subsequently Mercedes.
