The Reds will play LASK, Union Saint-Gilloise, and Toulouse in Group E.
Jurgen Klopp's men, who are favorites for the trophy, begin their campaign away to LASK on Thursday, September 21, and have now submitted their squad to UEFA.
Teams are allowed to select 25 List A players, but Liverpool are only able to name 23 due to their lack of homegrown players.
The limitation of 17 overseas players in the Europa League is one fewer than allowed in the Premier League, meaning someone had to be left out. Third-choice goalkeeper Adrian drew the short straw and has been excluded, with Vitezslav Jaros named alongside Alisson and Caoimhin Kelleher.
