Teams receive three points for a win and one point for a draw.

(d) Superior goal difference from ALL group matches.
(e) Higher number of goals scored.
(f) Coefficient points accumulated by the club in question, as well as its association, over the previous five seasons.
In the last 16:
(a) Clubs from the same association cannot be drawn against each other.
(b) The winners and runners-up of the same group cannot be drawn against each other.
(c) The group-winners cannot be drawn against each other.
(d) The runners-up cannot be drawn against each other.
(e) The runners-up must play the first leg at home.
