Thorgan Hazard saw his new team-mates lose to a team who play in the fifth tier of German football.
The younger brother of Eden has been sensational for the past two seasons in loan spells at Belgian Pro League side Zulte-Waregem. Voted the best player in the competition he is now hoping to have a similar impact on the German game.
And he has chose a good team to do it with. Gladbach have been busy this summer, securing the signatures of Yann Sommer, Ibrahima Traore, Andre Hahn and Fabian Johnson as they bid to launch an assault on the top four spaces in Germany.
But today they looked far from a Champions League outfit. Gladbach played their first pre-season game of the season against SSVg Velbert.
The club currently play in the Oberliga, Germany's fifth tier. This comes after they finished bottom of the Regionaliga West division last season - so this should have been a walk in the park for Gladbach.
But a goal from Huzefye Dogan, a former German youth international who played with the likes of Jermaine Jones, Tom Starke and Andreas Hinkel at the 2001 World Youth Championships, was enough for the minnows from the fifth tier to defeat Hazard's new team.
The team was not their best XI. The likes of Christoph Kramer, Granit Xhaka, Sommer and Johnson were unavailable. But Hahn, Traore, Luuk De Jong, Havard Nordtveit, Max Kruse and many more first-team regulars did feature - in an embarrassing result for the Bundesliga side.
