The midfielder played a full shift in the Elephants' second group game against Benin and took over the captain's armband when Didier Drogba was substituted in the second half.
Ivory Coast cruised to a 4-1 win in Ghana's Sekondi Sports Stadium with goals from Drogba, Ya Ya Toure, Keita and Dindane.
They top Group B with two wins in two games with Mali to come in the final group match on Tuesday.
The top two teams from four groups progress to the quarter-finals of the tournament.
It's so far, so good for Didier Zokora and the Ivory Coast in the African Cup of Nations.
