Ronaldinho complained of the team's tactics after a 1-1 draw against Sport in its opening match in the Brazilian league this weekend, irritating coach Joel Santana.
The former South Africa coach Santana hinted the team disappointed because Ronaldinho didn't play well.
Ronaldinho has been criticized by fans and local media for his poor performances and the team's disappointing results this year, and there have been talks about the player possibly leaving the club.
It doesn't help that Flamengo has been struggling to pay for the player's high salary, prompting Ronaldinho's agent to complain.
