The 29-year-old defender arrives after a spell with Tanzanian side Simba SC and brings a wealth of continental experience to the CECAFA Kagame Cup champions.
Ouattara has previously featured for Moroccan powerhouses Wydad Casablanca and Sudanese club Al Hilal Omdurman, among other sides. Known for his physical presence and defensive organisation, the Ivorian international is expected to strengthen Rayon Sports’ backline as they prepare for the new season.
The move marks a new chapter for Ouattara in Rwandan football, where he will look to contribute to Rayon Sports’ ambitions on both the domestic and regional fronts.
Rayon Sports continue to bolster their squad following their recent CECAFA Kagame Cup success, with Ouattara becoming one of their latest high-profile additions.
