Struggling Marseille striker Brandao has admitted he is not content with a place on the bench at Stade Velodrome.
The 30-year-old only penned a new deal in the summer, which runs until 2013, but has failed to score in 11 appearances this season.
Poor form has seen the uncapped Brazilian relegated to the bench, prompting rumours he could force a move away from the club in January.
Brandao played a significant part in Marseille's run to the Ligue 1 title last term, scoring eight times, and he believes he merits his place on that basis.
"I can't be satisfied coming from the bench only for five or 10 minutes," Brandao, who has been attracting interest from Rubin Kazan, told L'Equipe.
"I came to Marseille to play, not to be a substitute. I can accept competition, but I can ask for more opportunities to play.
"I have already showed my potential in the past," added the former Shakhtar striker.
Marseille manager Didier Deschamps has not shut the door on the striker's future at the club, but insists he must up his game when given the opportunity to impress.
"He has played less often than last season," admitted Deschamps.
"He had some physical trouble and there is competition. I know what he is capable of and what he can bring to the team.
"But when I am playing him it is up to him to show he is the best and very efficient."
