The Bavarians, who had scored a total of 20 goals in their previous four home games in the competition this term, came close to a second goal in the 71st but Mueller's diving header went wide.
It was left to Villarreal, Europa League winners last year, to punish the hosts with a sucker punch through Nigeria winger Chukwueze, to reach the semis for the first time in 16 years.
"If you want to achieve something in this competition you need to beat the big teams," Emery said. "We took the first step (in the last 16) with Juventus. With Bayern, we analysed the game well."
"Now Benfica or Liverpool it is the same. We have a semi- where we will try to use our chances," he added.
