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 in to the Europa League.
