Bayern Munich midfielder Xabi Alonso has asked his teammates to take Benfica seriously.
Bayern had to claw back from 2-0 down to win 4-2 on the night and 6-4 on aggregate against Juventus to qualify for the last eight.
In this same stage last season, Bayern were paired with Porto and fell to a 3-1 defeat in the first leg and staged an amazing comeback in the second leg, winning 6-1 at Allianz Arena.
“We have learned from the experience of last year against Porto – at this stage everyone is difficult,” the Spaniard said.
“Of course there are bigger names, but we have to focus on our tie; you can’t take anything for granted.
“We came through a tough tie against Juventus and need to keep going. We have to respect Benfica, but we have plenty of time to analyse them.”
