Zenit complete the pot one line-up as the Russian Premier League champions are designated by UEFA to be given a place among the other top seeds.
That means last season's beaten finalists Tottenham go into pot two with the two Madrid clubs, as well as Napoli, Shakhtar Donetsk, Benfica and Ajax – the 2018-19 semi-finalists who beat APOEL in the play-off round to secure qualification.
Club Brugge and Slavia Prague also came through the play-off round on Wednesday and they have been placed in the third and fourth pots respectively.
The draw will be made at the Grimaldi Forum in Monaco, with the group stage set to get under way in mid-September while this season's final is scheduled for May 30 in Istanbul.
Pot one: Barcelona, Manchester City, Liverpool, Chelsea, Bayern Munich, Juventus, Paris Saint-Germain, Zenit
Pot two: Real Madrid, Atletico Madrid, Borussia Dortmund, Napoli, Tottenham, Shakhtar Donetsk, Ajax, Benfica
Pot three: Lyon, Bayer Leverkusen, Salzburg, Olympiacos, Club Brugge, Dinamo Zagreb, Inter, Valencia
