The Reds are in Group L, alongside Astana, AZ Alkmaar and Partizan Belgrade, as Ole Gunnar Solskjaer's men enter the competition we won in 2016/17.
We begin with a home match on Thursday 19 September, against Kazakhstan Premier League outfit Astana. Tickets are currently available for this opening encounter at Old Trafford, which kicks off at 20:00 BST.
Due to the tournament rules, the squad is broken down into four sections: A List, Club Trained, Association Trained and B List.
Please note that the B List is not presented below, as it may contain an unlimited number of players and is made up of homegrown youngsters who can be called upon during the competition.
