Manchester United learned their three Europa League opponents on Friday.
AZ Alkmaar, Astana and Partizan Belgrade are the three teams we will meet twice between now and December.
Ahead of the Group L matches, we have taken a look at how all three teams are faring domestically.
AZ suffered a 2-1 defeat at the weekend away against surprise Eredivisie leaders Vitesse, conceding a last minute winner.
Teun Koopmeiners scored AZ’s goal from the penalty spot, and it was just one three shots they had on target despite having 61 per cent of possession.
AZ are in seventh place with two wins from four matches, and have played a game less than some of their competitors.
They had to qualify to reach the Europa League, and needed extra time to get back Royal Antwerp in the final round. They previously beat Ukrainian side Mariupol and Swiss club BK Hacken.
AZ’s best known player is veteran Dutch centre-back Ron Vlaar.
Kazakhstan’s most famous club had to get through a tough qualifying tie to reach the Europa League group stages.
They beat Belarussian champions BATE Borisov, winning 3-2 on aggregate.
Astana won the home game 3-0, which is a warning that United will be in for a tough game in between the 6,000 mile round trip.
Domestically Astana sit fourth in Kazakhstan’s Premier League, five points off the top with two games in hand.
The player to watch is 32-year-old Croatian winger Marin Tomasov, who has 11 goals and 14 assists in 23 league games this season.
Partizan knocked out Ole Gunnar Solskjaer’s former side Molde in the qualifying rounds, winning 3-2 on aggregate.
At the weekend Partizan drew 1-1 at home with Serbian league leaders Backa Topola.
On loan Roma striker Umar Sadiq, formerly of Rangers, scored Partizan’s goal.
The draw kept up Partizan’s unbeaten domestic form to start the season.
They have won three and drawn two of their opening five games and sit in seventh place in the Serbian SuperLiga.
In addition to Molde, in the qualifiers, Partizan knocked out Welsh side Connor’s Quay Nomads, who had surprisingly beaten Kilmarnock.
