Liverpool's surge to a sixth European title helped Virgil van Dijk beat Ronaldo and Messi to Uefa's Player of the Year award at the ceremony in Monaco after the group stage draw.
Liverpool's title defence starts with a group that again includes Napoli, who Jurgen Klopp's side had to beat last December to advance to the knockout stage. Salzburg and Genk also await in Group E.
For Paris Saint-Germain and Manchester City — among the biggest-spending teams of the past decades thanks to investment by state-linked ownership from the Persian Gulf — the quest for a first Champions League title will have contrasting assignments.
Tough for PSG after being paired in a group with a Real Madrid side chasing a record-extending 14th European crown. Relatively straightforward for City, placed in a group with no former champions and that includes newcomers Atalanta.
In Group A, PSG will also face Club Brugge and Galatasaray.
In Group C, City will also take on Shaktar Donetsk and Dinamo Zagreb while facing doubts about their Champions League participation next season as the Abu Dhabi-owned team is investigated for Financial Fair Play breaches.
One of the most eye-catching groups is F. Barcelona, who last won the competition in 2015, were drawn with former champions Borussia Dortmund and Inter Milan, alongside Slavia Prague.
Bayern Munich, who have won the European Cup five times, like Barcelona, are in Group B with beaten 2019 finalists Tottenham, Olympiakos and Red Star Belgrade.
Ajax, who had to go through qualifying to reach the group stage, were drawn with Chelsea, who qualified as Europa League champions, Valencia and Lille in Group H.
Group G seems the least appealing for global television audiences: Zenit St Petersburg, Benfica, Lyon and Leipzig.
