The German coach rested some of his star men for the trip to the AWD Arena but they still racked up another convincing win, thus underlining their incredible strength in depth
The former Real Madrid coach opted to rest a number of key men ahead of Tuesday's mouth-watering Champions League semi-final showdown with Barcelona, including Bastian Schweinsteiger, Philipp Lahm and Javi Martinez.
However, Bayern still ran riot at the AWD Arena, much to the delight of Heynckes who feels he is in possession of a squad to rival any other in Europe.
"The players have proven time and again that we have no B team, only an A team," the 57-year-old German is quoted as saying by his club's official website.
"The players simply have fun playing football and have a great attitude. All of them are highly motivated. We had a lot of great play, showed great discipline and scored a lot of goals.
"We laid the foundation for this big win in the first half."
Meanwhile, Bayern goalkeeper Manuel Neuer believes that the win in Hannover has set the newly-crowned Bundesliga champions up nicely for the visit of the Blaugrana.
"We wanted to prepare well for the game against Barcelona," the Germany international admitted. "And we succeeded!
"We played well and brought a convincing performance, especially in the first half."
Bayern's eagerly-awaited clash with Barca will kick off at 20.45CET on Tuesday.
