The 24-year-old had equalled the previous record of 51 held by Germany's Anja Mittag in the first leg of the last-16 tie against the Danes, which the defending champions won 4-0 earlier this month.

Hegerberg, playing her 50th game in the competition, then hit the record-setting goal in the 12th minute of the second leg on Wednesday before adding a second on the night.
