The 2005 Ballon d'Or winner did not show up for training after being handed an extra day off, but reports of a bust-up between player and club persist
The playmaker was expected in Rio de Janeiro on Tuesday to resume training, but failed to do so.
After initially remaining tight lipped, the Rio giants revealed that Assis, Ronaldinho's brother and agent, had asked for an extra day off.
However, rumours suggest that the former Barcelona man is keen to leave the club after being substituted and insulted by club fans in a match against Internacional. He is also said to believe that some figures within the club are trying to force him out.
And further reports suggest that Assis recently wanted Ronaldinho to quit Flamengo as soon as possible, but the former Milan man was keen to remain in Rio de Janeiro and decided to stay.
But now that the relationship between the player and club appears to be more tense than ever, with Rio's press reporting that his agent is already negotiating with foreign clubs.
