Some have questioned the wisdom of Roma handing Totti a deal which will eventually see him become a director in 2014.
But Mazzone said: "I cannot but be happy. I am tied to Francesco by a special, splendid relationship and to know that it crowns a dream of his makes me happy.
"But beyond the human aspect, I believe that it's splendid news also from a technical point of view. Despite the many injuries, Totti always offers performances that are superior to the average."
