The teams that advanced to the European Cup were all selected through European qualifiers. However, the semi-finals of the Europa League will be divided into four groups as seed teams in the European Cup qualifier draw.
There are 24 seats in the European Cup, 20 of which are directly produced by the European preliminaries.
The remaining four seats are closely related to the Europa League. The remaining four places in the European Cup should come from the top 16 teams in the Europa League A, B, C and D levels. However, if there are qualified teams in the former 16, the opportunity to participate in the play-offs will be postponed to other teams in turn.
