Thomas Muller hailed Bayern Munich's efforts after the Bundesliga leaders responded to a 5-0 thrashing by Borussia Monchengladbach with victory over Union Berlin.
Gladbach handed the Bavarian giants a shock demolition in the DFB-Pokal on Wednesday, the first time Bayern had lost by a five-goal margin since December 1978.
However, Julian Nagelsmann's side responded well with a 5-2 win against Union, who had gone 21 home league games without defeat before facing the reigning champions.
Leroy Sane added to Robert Lewandowski's first-half brace to put Bayern three ahead before Niko Giesselmann and Julian Ryerson struck either side of Kingsley Coman's finish.
Muller, who has scored against all the other 17 current Bundesliga teams bar Bayern, then netted to seal victory while adding Union to his list – the 26th side he has scored a top-flight goal against.
The 32-year-old was one of the more vocal figures after the Gladbach thrashing and he once again defended his team-mates and club after Saturday's game.
"You don't have to work on every little detail now," Muller told reporters post-match.
"If FC Bayern crashes out of the cup with a 5-0 loss, you have to be able to learn something, we're not made of sugar.
"Sometimes there is criticism that is a little below the belt. But we are not standing here comfortably.
"We are still out of the cup, the competition was very important to us. It's certainly not all great now."
Muller also explained how Bayern were expecting a tough task, given Union's impressive home form and the fact they had taken 16 points after nine games – their best return, joint with last season, in a top-flight season.
"We had to show a reaction," he continued. "Here in this stadium you never know what's going to happen.
"We had to accept the duels and take responsibility that everyone wanted the ball.
"We played a very dominant game, we should have scored a few more goals.
"Then came the Union response, they fought back and showed even more aggressiveness, played long balls but we gave the right answers with the goals."
