Moussa Tandian, working for leading Cameroonian independent broadcaster Equinoxe, asked Eto'o if he believed the current generation were coming to the end of their time with the Indomitable Lions.
"I'm rather surprised, dear brother, because you are making yourself noticed negatively," Eto'o said. "You should rather think about excusing yourself."
Eto'o said Tandian should "thank" Cameroonian players for their performance.
"I think that you are not Cameroonian," he went on. "I will speak to your boss at Equinoxe because you don't deserve to work for this wonderful channel.
"You journalists, certain journalists like you, you who do not want Africa to advance, you who do not want Cameroon to advance, you are always negative, try to change a little," he said, as he pointed to Tandian.
Eto'o later apologized to Tandian, according to Théophile Biamou, a top executive for Equinoxe.
"There are no bad questions," Biamou told The Committee to Protect Journalists after the apology. "There are rather bad answers."
