Barcelona, winners of the 2020/21 UEFA Women's Champions League, begin their quest to recapture the title at home against Benfica as Group D of the 2022/23 kicks off.
The Blaugrana, who lost to Lyon in the Turin final last season, have reached the showpiece of this competition in three of the last four seasons – also being beaten by the French outfit in 2019 before defeating Chelsea in emphatic fashion two years later.
Barça extended their record haul of Primera División titles last term with their third in succession and seventh overall – winning all 30 of their league games in the process and scoring 159 goals along the way.
Benfica, who became the first Portuguese side to reach the last 16 of this competition in 2021/22, finished third in last season's Group D behind eventual champions Lyon and Bayern München, with whom they drew 0-0 in their opening group match.
As Águias, who sealed back-to-back Campeonato Nacional Feminino titles last term, overcame Kosovan side Hajvalia (9-0) and Eredivisie holders Twente in Round 1 of qualifying. They then secured a 5-3 aggregate success against Scottish champions Rangers in Round 2, although they required extra time in the Lisbon second leg (3-2 a, 2-1 h aet).
