The2017–18 UEFA Champions League was the 63rd season of Europe's premier clubfootball tournament organised byUEFA, and the 26th season since it was renamed from the European Champion Clubs' Cup to theUEFA Champions League.
Thefinal was played betweenReal Madrid andLiverpool at theNSC Olimpiyskiy inKyiv, Ukraine.[5] Real Madrid beat Liverpool 3-1 to win a record-extending 13th title, their third title in a row and fourth in five seasons.
As winners, Real Madrid qualified as the UEFA representative for the2018 FIFA Club World Cup in the United Arab Emirates, and also earned the right to play against the winners of the2017–18 UEFA Europa League,Atlético Madrid, in the2018 UEFA Super Cup, winning the former. Additionally, they would have been automatically qualified for the2018–19 UEFA Champions League group stage,[6] but since they had already qualified through their league performance, the berth reserved was given to the champions of the2017–18 Czech First League, the 11th-ranked association according to the 2018–19 access list.[7]
79 teams from 54 of the 55UEFA member associations participated (the exception beingLiechtenstein, which did not organise a domestic league).[8] The association ranking based on theUEFA country coefficients was used to determine the number of participating teams for each association:[9]
Associations 1–3 each had four teams qualify.
Associations 4–6 each had three teams qualify.
Associations 7–15 each had two teams qualify.
Associations 16–55 (except Liechtenstein) each had one team qualify.
The winners of the2016–17 UEFA Champions League and2016–17 UEFA Europa League were each given an additional entry if they did not qualify for the 2017–18 UEFA Champions League through their domestic league. Because a maximum of five teams from one association could enter the Champions League, if both the Champions League title holders and the Europa League title holders were from the same top three ranked association and finished outside the top four of their domestic league, the fourth-placed team of their association was moved to the Europa League.[10] For this season:
The winners of the2016–17 UEFA Champions League,Real Madrid, qualified through their domestic league, meaning the additional entry for the Champions League title holders was not necessary.
The winners of the2016–17 UEFA Europa League,Manchester United, did not qualify through their domestic league, meaning the additional entry for the Europa League title holders was necessary.
Kosovo, who became a UEFA member on 3 May 2016, made their debut in the UEFA Champions League.[11][12]
For the 2017–18 UEFA Champions League, the associations were allocated places according to their 2016UEFA country coefficients, which took into account their performance in European competitions from 2011–12 to 2015–16.[13][14]
Apart from the allocation based on the country coefficients, associations could have additional teams participating in the Champions League, as noted below:
(UEL) – Additional berth for UEFA Europa League title holders
In the default access list, the Champions League title holders entered the group stage.[12] However, sinceReal Madrid already qualified for the group stage (as the champions of the2016–17 La Liga), the Champions League title holders berth in the group stage was given to the Europa League title holders,Manchester United.[15][16][17][18] and the following changes to the default allocation system are made:

Pot 1 contained the title holders and the champions of the top seven associations based on their 2016UEFA country coefficients.[13][14] As the title holders,Real Madrid, were one of the champions of the top seven associations, the champions of the association ranked eighth (Ukraine'sShakhtar Donetsk) were also seeded into Pot 1 (regulations Article 13.05).[9]
In each group, teams played against each other home-and-away in around-robin format.
