Bayern Munich had Barcelona's Champions League collapse in mind as they closed out a semi-final place at Sevilla's expense, according to experienced winger Arjen Robben.
A goalless draw on Wednesday at the Allianz Arena was enough to seal a semi spot for the sixth time in the past seven seasons for Bayern, who were 2-1 winners against the LaLiga side last week.
Jupp Heynckes' men join Liverpool, Roma and Real Madrid in the semi-finals.
Madrid needed a controversial stoppage-time penalty from Cristiano Ronaldo to see off a phenomenal Juventus comeback, while Roma's 3-0 win at the Stadio Olimpico on Tuesday saw them improbably dump out Barcelona on away goals.
"Of course that was a warning," Robben told reporters. "It shows that everything can happen in football.
"If you play at this level, you need a top performance. That will be the case in the semi-final.
"We are now in the semi-finals in the Champions League and in the DFB-Pokal. We have to go a bit further.
"In the semi-finals there are no favourites. We have to see who we get tied up with and then prepare well. There are only good teams left."

Robben conceded it was not a vintage Bayern performance but the Bundesliga champions rarely lost control of the action.
"From the outside, maybe 2-1 away felt as if it was almost done but we knew that they have a good team," he added.
"In the first half we had some trouble in midfield. Then they have quality and they can play.
"They had a few chances. In the end we had more chances, but what was missing was a goal. We should have scored a goal."
