How does the new format work?

The expanded 36-team tournament sees each team play eight games – four at home and four away – in the league system, against two opponents from each of the four seeding pots.

Teams who finish in the top eight will qualify automatically for the last 16, while those who place ninth to 24th will compete in a two-legged knockout play-off for the chance to join them.

Whoever finishes 25th or lower will be eliminated and will not be entered into the Europa League.

The number of matches in the new format will increase from 125 to 189.

Each team will play a minimum of eight games – instead of six – and a maximum of 17.

Champions League action begins on 17-19 September, and with the increased number of fixtures, the league phase runs until 29 January rather than finishing before Christmas.
