Cameroon pair Joel Matip and Allan Nyom will regret missing the Africa Cup of Nations and should have listened to Bob Marley, according to El Hadji Diouf.
Cameroon are in the final despite West Brom's Nyom and Liverpool's Matip being among eight players to refuse call-ups.
"I don't understand people turning down their country," former Senegal striker Diouf told BBC World Service.
"And like the legend Bob Marley always said 'if you don't know where you come from, you don't know where to go'."
Cameroon beat Ghana 2-0 in Thursday's semi-final in Gabon to book a final meeting with Egypt on Sunday.
