Hosts Ivory Coast leave Zaha out of African Cup of Nations squad
Zaha, who moved to Turkey from Crystal Palace in the close season, has only played in two friendlies for Ivory Coast this year, missing their Cup of Nations qualifiers and last month's first round of World Cup qualifying.
Gasset has included Nottingham Forest's Serge Aurier, Ibrahim Sangare and Willy Boly plus Al Ahli midfielder Franck Kessie and Trapzonspor winger Nicolas Pepe, who returns after a year's absence.
Hajduk Split's Chester Diallo got a first call-up, while Union Saint Gilloise's Lazare Amani makes his second squad.
Forwards Sebastien Haller of Borussia Dortmund and RB Salzburg's Karim Konate also feature for the hosts, who face Guinea Bissau in the tournament's Jan. 13 opener.
They also play Nigeria and Equatorial Guinea in Group A.
