After a flying start, Der BVB have been treading water in recent weeks, not winning in the Bundesliga since September, and they've only taken two points from five Champions League games.
Wednesday's trip to the Bernabeu marks their final group stage game and anything but a win could see them crash out of Europe altogether, with APOEL also pushing for the Europa League place.
Real have already guaranteed second so may take their foot off the gas and may have an eye on matters beyond Wednesday's clash.
With boss Peter Bosz's future at the club in doubt, Schurrle admits Dortmund need a good showing to restore some pride after a shocking last few months.
"We want to put in a good performance," said Schurrle. "This match is a big challenge for us. We'll need to run, we'll need to fight, we'll need to win the tackles and we'll need to create goalscoring chances if we are to gradually pull ourselves out of the hole we are in."
The World Cup winner's side currently sit sixth in the Bundesliga table but with the quality available, punters may back them to turn things round and use their free bet to back them to finish in the top three.
