The previous group stage of eight groups consisting of four teams each has been ditched in favour of a new league format.
All of the 36 teams have been separated into four pots and will draw two from each. They will face eight different opponents, playing four matches at home and four away.
Arsenal are in Pot 2 for the draw, meaning they could face the likes of holders Real Madrid or Paris Saint-Germain from Pot 1.
The draw takes place on Thursday at 5pm BST and much of it will be automated due to the sheer number of fixtures to be organised.
Tuesday’s play-off ties will decide the final clubs in the hat before Mikel Arteta learns who will be heading to the Emirates Stadium in what promises to be one of the most fascinating European campaigns of all time.
Which pot are Arsenal in for the Champions League draw?
Arsenal have been placed in Pot 2, as their current coefficient has them sat 19th in UEFA’s rankings for European teams.
Who can Arsenal face in the Champions League draw?
The ceremony will produce eight opponents for every team, two from each pot. That means Arsenal will play two of the top-ranked clubs.
They cannot play a team from their own country (Aston Villa, Liverpool or Manchester City) at this stage and can only play a maximum of two teams from each other country.
Pot 1: RB Leipzig, Real Madrid, Barcelona, Bayern Munich, PSG, Inter Milan, Borussia Dortmund
Pot 2: Bayer Leverkusen, Atletico Madrid, Atalanta, Juventus, Benfica, Club Brugge, Shakhtar Donetsk, AC Milan
Pot 3: Feyenoord, Sporting CP, PSV, Celtic, Young Boys, Dinamo Zagreb or Qarabag, Lille or Slavia Prague
Pot 4: Sparta Prague, Monaco, Bologna, Girona, Stuttgart, Sturm Graz, Brest
Pot to be decided: Midtjylland or Slovan Bratislava, Bodo/Glimt or Red Star Belgrade, RB Salzburg
