Seven-time European women’s champions Lyon thrashed Benfica 5-0 in Lisbon on Thursday as Barcelona, who took the crown last season, also scored an impressive away victory, 4-0 at Arsenal.
Lyon locked up their place in the knockout stages with one round of group games to play, while Barca ensured they will progress as group winners.
In Lisbon, Norwegian Ada Hegerberg headed Lyon into the lead after 34 seconds from a cross by Delphine Cascarino.
Centre-back Wendie Renard headed the second, meeting a corner under the Benfica crossbar in the 27th minute.
In the 40th minute, Hegerberg again won the ball in the area and nodded it down to Griedge M’Bock who volleyed against the post and then scrambled in the rebound.
