Manchester United will face Fenerbahce, Feyenoord and Zorya Luhansk in the group stage of the Europa League.
It pits United against their former striker Robin van Persie, who is now with Fenerbahce.
Southampton, the other Premier League side still in the competition, will play Inter Milan, Sparta Prague and Hapoel Beer Sheva.
League of Ireland side Dundalk have been drawn with Zenit St Petersburg, AZ Alkmaar and Maccabi Tel-Aviv.
United boss Jose Mourinho said he knew little about Ukrainian opponents Zorya but welcomed being drawn with Fenerbahce and Feyenoord.
“We all know the competition is not the same as the Champions League but to have Manchester United playing against clubs with tradition like Fenerbahce and Feyenoord is good for us,” he said.
“We know that it will be a difficult group, but I think that is a good thing. It is good for the fans and for the players because it will help motivation.”
