The two teams met in three European ties during the 1970s, beginning with the 1973 UEFA Cup final, and a lasting friendship between the two sets of supporters was formed.
This will be the 27th annual visit to Anfield made by the German side's official supporters' club, who - with the Bundesliga paused for a winter break - will cheer on the Reds against Wolverhampton Wanderers on Sunday.
Today, December 28, there will also be a pub tour as supporters from both clubs mark the festive celebrations.
The 13th annual LFC supporters' visit to Gladbach will take place during the spring of 2020.
