Borussia Dortmund crashed to a 2-0 defeat against Augsburg in the Bundesliga earlier.
The German Giants will be thoroughly disappointed with their display away from home today and it will be interesting to see if they can bounce back with a positive result in their next game against Bayern Munich.
Dortmund were favourites heading into the game and they were expected to win without any problems.
There is no doubt that they have the better set of players and the fans would have expected a far better performance from them.
Dortmund will be hoping to challenge Bayern Munich for the German League title this year but they will have to improve their performance immensely if they want to do so.
A team hoping to win the League should be getting three points out of these matches.
Udokhai scored the opening goal of the game for the home side on the 40th minute.
The hosts doubled their tally 14 minutes into the second half when Caligiuri struck the second goal of the game.
Borussia Dortmund have one of the best attacking units around Europe and they should be putting these defences to the sword every week. The visitors lacked the cutting edge today and the likes of Haaland and Sancho failed to convert their chances.
