The UEFA Europa League pots for the group-stage draw have now been finalised.
Manchester United and Arsenal are in Pot 1 for Friday’s Europa League group-stage draw.
The group-stage draw will be held at midday BST, with the 32 teams placed into eight groups of four teams.
No two teams from one country can be in the same group, while Man United and Arsenal could come up against the likes of PSV, Monaco, Real Sociedad and Real Betis.
The winners of each group will advance directly to the Europa League round of 16.
All of the runners-up in the groups will take part in the knockout round playoffs, where they will face one of eight teams dropping out of the Champions League, having finished third in their respective groups.
