The four qualifiers were seeded according to performance in the pool stage - with the two best performing pool winners being ranked as seeds 1 and 2, while the third group winner and best group runner up were ranked as seeds 3 and 4. The top four seeds hosted the quarter-finals against the lower seeds, in a 1 v 4, 2 v 3 format. However, if two teams qualified from the same pool they could not be drawn together. For the final the highest ranked seed would have home advantage.Teams were ranked by:
