Chelsea boss Liam Rosenior says Fernandez won't be considered for selection for their FA Cup quarterfinal against Port Vale this weekend and next week's crunch Premier League clash with Manchester City.
Rosenior insists the Argentine "crossed the line" for talking up a move to Real Madrid on multiple occasions with Argentine reporters.
Agbonlahor said on talkSPORT: "I like it.
"It shows no player is bigger than the club, and people have been mocking Liam Rosenior that he's a yes-man, that's why they brought him in.
"But he's made a big choice here because Enzo Fernandez, World Cup winner, probably a big character in the dressing room to drop him for two important games.
"Yes, Port Vale, they win without him, but Manchester City is an important game - Chelsea need top five.
"They need their best players, so to drop him for that, I rate it highly from Liam Rosenior and the football club."
