Dida - Good keeper when he wants to be, but makes mistakes when he's low on confidence. A confidence keeper.
Cafu - Old, but still capible of matching anyone for speed and ability.
Lucio - Solid player.
Juan - Never heard of him.

Roberto Carlos - Past it imo. He just doesnt do what he used to anymore. Serginho, like most of the Brazilian public think, should be in Carlos's place.
Emerson - Strong player, but Gilberto Silva should be in his place.
Ze Roberto - Solid player, but not quite good enough for the first team imo.
Kaka - Brillient player that cuts out the fancy stuff to get the job done.
Ronaldinho - Brillient player, but as a drawback of his abilitys, he spends more time trying to show off than being beneficial to the team. Needs to learn that the basics are often enough.
Ronaldo - When he wants to, he's fantastic, but he hasnt shown any of his old form in ages.
Adriano - Good player, but like Dida, is a confidence player. When he's confident, he's as good as anyone.
