Now that the group-stage draw has been completed, the UEFA Europa League pots are set.
The Europa League group stage draw will be held on Friday, and Pot 1 includes Manchester United and Arsenal.
The 32 teams will be divided into eight groups of four teams for the group-stage draw, which will take place at noon BST.
Man United and Arsenal might play teams like PSV, Monaco, Real Sociedad, and Real Betis in their group; no two teams from the same nation may be.
Each group's victor advances directly to the round of 16 of the Europa League.
All of the group runners-up will compete in the knockout round playoffs, where they will play one of the eight teams who placed third in their respective groups but were eliminated from the Champions League.
