New SC Gagnoa owner, Tommy Tayoro Nyckoss, successfully persuaded Kalou to come out of retirement and join the club as their new player-director.
Kalou said: "I am going to get a player's licence, so that I can be part of coach Bernard Casoni's squad.
"And maybe if SC Gagnoa play against ASEC Mimosas or Africa Sports in the Ivorian Cup, I will take part in the game."
