It will be the very first encounter between Manchester United and RB Leipzig when last year's semi-finalists visit Old Trafford for our first home game of the group stage.
So, in order to become a bit more familiar with our new opponents, here's a breakdown of the German club's history, stadium, manager and the dates of our games...
HISTORY
RB Leipzig was established as a football club as late as 2009, when energy-drink producer Red Bull bought the license of fifth-tier club SSV Markranstädt and changed the name, logo and stadium. The goal was to make the Bundesliga within 10 years, however, it did not take as long for the Die Rotten Bullen to achieve their target.
