How does the new format work?
Each club will play eight matches in the opening phase - four home games and four away games against seeded opposition in a system designed to ensure that teams play opponents of similar difficulty.
Clubs will only face other sides based on the pot they have been drawn out of and teams cannot face more than two opponents from the same country or from the same association.
The top eight teams in the final table will automatically go through to the last 16.
They will then be joined by the eight play-off winners of ties between the sides who were placed ninth to 24th in the table.
Teams that finish 25th or lower will be eliminated from all European competitions this season - meaning that they will not drop into the Europa League similar to previous years.
Despite there being just eight matches in the opening phase, European matches will be spread over 10 midweek slots.
The new Champions League format also sees the implication of two additional qualifying spots.
