Gladbach welcomed Union, knowing that a win would take them back into the top 4 of the Bundesliga table.
The Foals dominated early on, and they got their reward 15 minutes in when Neuhaus was able to score after rounding Friedrich.
5 minutes before half time, they doubled their lead when Thuram was afforded a free header, after Pléa set him up.
Union came out strong in the second half, and got a goal through Andersson, who was able to head home after a set-piece.
But soon, Thuram added to his tally, as Pléa set him up again with a ball across the face of goal, and he was left with a tap-in.
