With Javi Martinez suspended for the game with the Turin giants, the 67-year-old is keen to test the Brazilian's effectiveness at the heart of midfield, as the Bundesliga front-runner prepares to combat the trio of Andrea Piro, Arturo Vidal and Claudio Marchisio on Tuesday in their first leg at the Allianz Arena.
"I think I will play Luiz Gustavo alongside Bastian Schweinsteiger, although I'm yet to discuss this decision with Luiz and Javi," Heynckes told reporters at a press conference.
Bayern enters the match knowing that victory over Hamburg and a defeat for Borussia Dortmund against Stuttgart would secure the Bundesliga title for the 23rd time in their history.
Heynckes also revealed he is wary of featuring Franck Ribery, after the France star suffered a toe injury in training on Thursday.
"If he doesn't feel any pain, then he plays. Yesterday, he did not take part in training, but did use the ergometer bicycle," Heynckes continued.
