Tottenham are celebrating reaching the next phase of the Champions League.
Tottenham booked their place with an almost effortless destruction of the Germans at White Hart Lane.
Gareth Bale missed a second-half penalty and rattled the woodwork twice before Crouch rounded off proceedings with a close-range tap-in with 11 minutes left.
Crouch told Sky Sports 1: "It's a great achievement, we want to give a good account of ourselves in the next round.
"It was a great team performance throughout the Champions League campaign: we have played very well and deserve to go through.
"Every big club wants to be in the Champions League playing against the best teams in the world.
"We want to get as far as we can for the fans and for us as well."
