The Brazil forward is allowed to train when he wants by Flamengo chiefs, which is upsetting some of his teammates.
"Adriano has the right to be treated in a different way, and if he decides not to train then he doesn't train. That's it," director Marcos Braz explained.
"Adriano is worth a sea of money and what he guarantees the club in terms of image and, above all, finances gives him the right to be treated in a different way with respect to all the other players.
"Go and ask all the components of the team if they agree or have problems with Adriano. They are all enthusiastic towards him. After all he is one of the players who worked the most in pre-season."
