The French Football Federation would only officially tell AFP that the 37-year-old, who was in the 1998 FIFA World Cup France™-winning squad, was a "hypothetical" choice to join Domenech's entourage as part of a revamp.
Boghossian, who played for Marseille, as well as Italian sides Parma and Napoli, will join a staff which includes Pierre Mankowski, Domenech's right-hand man. He will assume the role on 20 August, when France face Sweden in a friendly.
According to Le Parisien, "Boghossian will try to breathe a bit of new life into a France team which was sadly lacking in Switzerland", where they failed to progress beyond the first phase at UEFA EURO 2008.
Domenech was criticised in some quarters for the French showing, but the FFF has since confirmed the 56-year-old will lead their bid to reach South Africa 2010. Les Bleus' first qualifier is against Austria on 6 September.
Domenech took over from Jacques Santini as France manager after EURO 2004, and two years later guided the team to the FIFA World Cup Final, where they lost on penalties to Italy.
