Former Cameroon international Rigobert Song is in hospital after reportedly suffering a stroke.
A member of Song’s family told the BBC the 40-year-old was “unconscious” when he was taken to a hospital in Yaounde after suffering a “cerebral attack”.
Song played 137 times for his country and had spells with English clubs Liverpool and West Ham.
He has been working as the national team coach for Chad since his appointment in October 2015.
Former Cameroon team-mate Samuel Eto’o tweeted in French: “I wish you courage and a speedy recovery big brother.”
