Bundesliga - Bayern rule out Breno departure
The Brazilian started only seven Bundesliga matches last season due to fitness problems and his future at the club has been the matter of some debate.
However, Heynckes still has faith in the player who signed for Bayern from Sao Paulo in December 2007.
"Breno remains here, definitely," Heynckes told Kicker.
"I am hoping he is going to cope with the workload. This would be important as I need to have a good alternative choice in terms of central defence."
