Cordoba declared over the weekend it would be best if Balotelli left the club this summer.
The 19-year-old's agent Mino Raiola has now taken offence to Cordoba's comments.
He snapped: "Mario has not done anything wrong and has never discussed in public anything about Cordoba.
"Considering that Cordoba is nearly my own age, he should help raise the young players, not attack and envy them.
"If the old players are set against the young ones then what purpose does that serve to the group as a whole?"
