Rivera was not impressed by owner Gerry Cardinale, who has just supervised the resignation of coach Sergio Concukicao and Max Allegri.
He said to Libero: “The Americans still don't know much about football. They even sent Paolo Maldini away. Why did he never consider me?
“Maybe I was a nuisance because I never kept the words that my brain thought in my mouth!”
On teen striker Francesco Camarda was left on the bench last season, Rivera, who made his pro-debut with Alessandria at the age of 15, also: “Today it would be impossible to place a 15-year-old, at least here in Italy.
“You no longer see Rivera, (Francesco) Totti and (Alessandro) del Piero because they don't play. They are just the officers, they only do their own good. And sometimes the damage of football.”
