For the reigning Swedish champions, it will be a Nordic derby when they meet Norwegian Brann.
For Häcken, it was a nightmare opposition in the French Paris SG.
- It is clear that it is a great team.
It is clear that it will be tough for us, but we will give everything, says Jennifer Falk.
Only four teams are ready for the group stage already: Last year's winners Lyon, and the series winners from the three highest-ranked leagues, Wolfsburg, Chelsea and Barcelona.
Whether Rosengård and Häcken join them will be decided in the doubles meetings.
The two Swedish teams are in each part of the qualifying game.
As Swedish champions, Rosengård gets to go the so-called "champion route", where league winners from the fifth to seventh highest-ranked leagues get to face teams from lower-ranked leagues that advanced via a first qualifying round.
The total of 14 teams settle for seven places in the group stage.
In the second part, which is called the "league road", Häcken, as league runner-up in the women's league, has, like Rosengård, qualified directly for the second qualifying round.
The "league road" consists of ten teams, four of which have qualified there.
Five places to the group stage are at stake.
