Cisse, who led Senegal to the title in Cameroon two years ago, picked three players who have question marks over their conditioning but Dia was the biggest surprise when the squad was unveiled on Friday.
The forward looked to be out of tournament after being forced off with a thigh injury early in the second half of the Serie A clash between his Italian club Salernitana and AC Milan a week ago but Cisse was confident he would be ready, contrary to Italian press reports.
“If he is there, it’s because he is ready. I am sure that he will be available before our first match against Gambia,” the coach told a press conference on Friday.
Defender Youssouf Sabaly (30) was also named in the squad as he has returned to training at Real Betis - although he has not played since August. French-based midfielder Nampalys Mendy (31) will also be heading to Ivory Coast despite being sidelined in recent weeks.
Senegal begin the defence of their title against Gambia on January 15th and then play two more Group C matches against Cameroon and Guinea.
