And Le Roy, one of the most respected coaches in African football, with a record nine appearances at the continental showpiece has expressed his dismay at the latest decision by the world football governing body.
"Fifa's decision that June is a good time to host the Club World Cup means they are killing the Nations Cup," LeRoy told BBC Sport Africa.
"When they decided to make a world championship of clubs with 24 teams at the same time as the Africa Cup of Nations, it's terrible for the projection of this beautiful competition - the Nations Cup."
