Kouamé started playing football on the streets of Bingerville, a suburb of Abidjan, Ivory Coast. At the age of 16, he moved with other Ivorian teenagers to Italy to participate in trials with several clubs. Eventually he was signed by Prato and as still a minor at that time, grew up with an Italian foster family he is still close with.[1]
Kouamé made his professional debut in the Lega Pro for Prato on 6 September 2015 in a game against Pisa.[2]
