Farke says he has seen enough to feel positive about the challenges ahead.
"We are the underdog, but if we reduce our mistakes and are good in our attacking play we have a chance wherever we travel," he said at a press conference reported by the club.
"We have found it easier to get good results against top-class teams so far, instead of teams who like to sit deep and defend.
"We are respectful, but we are not scared. We need an outstanding performance.
"Pressure is on us in every game, so there is not much difference depending on who we play."
