There are two pots – one of seeded teams and one of unseeded teams.
No club can be drawn against a team that played in their group or a side from their own national association.
Seeded group winners are away in the round of 16 first legs on 12/13 and 19/20 February and at home in the return matches on 5/6 and 12/13 March.
The Champions League draw takes place on Monday.
