The experienced coach feels people should not read too much into his side's defeat to Bayer Leverkusen, as they prepare for their cup game against Kaiserslautern
The Bavarians were beaten 2-1 by Bayer Leverkusen after winning their opening eight games, but Heynckes does not believe Sunday's defeat will have a negative impact on his side in the coming weeks.
"We’re stable and this team is very performance-oriented. I have no concerns," Heynckes stated at a press conference.
"We need to deal with the situation coolly and not start imagining the worst.
"The team is still entirely in one piece, and will continue to demonstrate as much over the coming weeks."
Bayern will be looking to return to winning ways in Wednesday's DFB-Pokal match at home to Kaiserslautern.
