Ajara Nchout was on target twice for Valerenga as they humiliated KI 7-0 in Wednesday's Women's Champions League qualifying round at Intility Arena.
Nchout was afforded a start for the Portuguese side on her return to the elite European competition since her last outing with Russian giants Rossiyanka in 2013.
The Cameroon international performed creditably well for Jack Majgaard's side and she contributed a brace to power her side to the Round of 32 on their maiden outing in the 2020-21 campaign.
Synne Jensen opened the scoring from the spot after just 23 minutes into the match before Nchout doubled the lead two minutes later.
