How many teams qualify for the knockout phase?published at 13:54 Greenwich Mean Time 28 January
Here's a reminder of what the 36 league-phase teams are aiming for.
Those finishing in the top eight automatically progress to the last 16, where they will be seeded.
They will await the winners of eight two-legged knockout play-off ties featuring the clubs ranked from ninth to 24th.
Those finishing between ninth and 16th will be seeded and face a team placed 17th to 24th, with the advantage of playing the second leg at home.
The clubs 25th or lower are eliminated and do not gain entry to the Europa League.
The play-off ties take place mid-February, with the last-16 matches in the first two weeks of March.
