Six British sides will be involved when the draw for this season's Champions League group phase is made on Thursday.
Premier League champions Chelsea, Tottenham and Manchester City had already qualified, while Manchester United's Europa League final win over Ajax in May sealed their place.
Celtic are also through after an 8-4 aggregate win over Kazakh side Astana in the play-off round, with Liverpool securing their place by beating Hoffenheim on Wednesday.
But who could each team play? And how might the clubs' routes to the final in Kiev differ?
As always, there are 32 teams taking part at this stage of the competition, with the draw splitting them into eight groups of four from four seeded pots.
The first pot always contains the reigning champions - in this case Real Madrid - plus the title winners from each of the seven highest-ranked leagues in Europe.
Given Spain are among the top seven and Real are already included, that means the eighth country is also represented this season, with Ukrainian team Shakhtar Donetsk placed among the leaders.
Pots two, three and four are based purely on coefficients calculated using points gathered in European fixtures over the last five seasons, with more recent results carrying more weight.
That means while Feyenoord are a well-known name, this is their first appearance in the Champions League groups for 15 years and they're in the final pot as a result.
A total of 22 teams qualify automatically, with 10 more sides coming through up to four preliminary rounds.
The others guaranteed a place are the winners of Europe's top 12 leagues, runners-up from the first six and third-placed teams from the Premier League, La Liga and the Bundesliga.
As Premier League champions, Chelsea are the only English side among the top seeds, with the days of more than one side from the same country being listed in the top eight now gone.
Manchester City and Manchester United both have better coefficients than pot one sides Monaco, Spartak Moscow and Shakhtar but have to settle for places in pot two.
Tottenham will be in pot three and Liverpool joined them with their 6-3 aggregate win on Wednesday, meaning Celtic stay in pot four.
Celtic could face any of the five Premier League teams. Of course, there are a multitude of possible combinations for each side and they range from being exceptionally difficult to something many see as comfortable.
Chelsea, for example, could end up in a group with the likes of Porto, Basel and Qarabag, which most would expect them to advance from.
At the other end of the scale, Celtic could find themselves pitched against Bayern Munich, Barcelona and Napoli if they stay in pot four.
This season's group phase runs, as it usually does, from mid-September to early December, with the knockout stages of the competition coming in 2018.
The opening games will take place on September 12 and 13 - and in Atletico Madrid's case that may well see them play at their new Wanda Metropolitano home for the first time.
After that, matches are played on September 26/27, October 17/18, October 31/November 1, November 21/22 and December 5/6.
The top two from each group will move on to the round of 16, with the draw for that taking place in December and games starting at that stage in February.
