All league phase matches are played in accordance with the league system, whereby each club plays six opponents in single-leg ties. Each club plays three home and three 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 18 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 4 at the end of league phase qualify for the quarter-finals. The clubs ranked 5 to 12 qualify for the knockout phase play-offs. The clubs ranked 13 to 18 are eliminated.
