All league phase matches are played in accordance with the league system, whereby each club plays eight opponents in single-leg ties. Each club plays four home and four away matches.
In principle, a club does not play more than two home or two away matches in a row and each club plays one home match and one away match across the first two matchdays and across the last two matchdays. The UEFA administration may derogate from these rules if necessary.
All 36 clubs are ranked in a single league ranking according to their results (3 points for a win, 1 point for a draw, 0 points for a loss).
The clubs ranked 1 to 8 at the end of league phase qualify for the round of 16. The clubs ranked 9 to 24 qualify for the knockout phase play-offs. The clubs ranked 25 to 36 are eliminated.
