Aguero, who played for the club between 1997 and 2006, has reportedly offered to buy five new players after the 16-time Primera Division winners were relegated last term.
Dad Leonel revealed: "Sergio Aguero offered to buy 5 players and pay their salaries.
"We asked Carlos Squeo (assistant coach to manager Miguel Angel Brindisi) for a list of players. We don't know what players they want because no-one called back.
"Not Squeo, not (general manager Miguel Ángel) Brindisi. No leadership. I feel there is a slight against Sergio."
