Recent reporting suggested that Chelle was ready to depart his post following their defeat to the Democratic Republic of Congo in their World Cup play-off encounter.
Moroccan television outlet Le7TV said that Chelle is a contender to replace Amine Benhachem at the second-placed Botola Pro 1 side.
Efoghe though has moved to end the speculation, telling journalists in a group chat: "Good day, friends and colleagues. Kindly ignore this story. It is fake news."
The Nigeria Football Federation, meanwhile, posted photos of coach Chelle with the caption: "EC is focused on the task ahead".
Chelle has one year left on his current contract with Nigeria.
