Republic of Ireland striker Kyra Carusa was named player of the match as HB Koge earned their first Champions League win of the campaign with a 5-1 thumping of Servette Chenois.
On Tuesday Carusa was named in Carla Ward's Ireland side for the upcoming World Cup play-off semi-final against Kazakhstan, and she looked in top form for the Danes tonight.
HB Koge were beaten by Arsenal in their opening game of the competition but bounced back when Macy Schultz put them in front with a cool flicked finish just nine minutes in.
They extended their advantage with two further goals before the break when Nadia Nadim nodded home from Carusa's cross and Noemie Carage turned the ball into her own net.
Servette responded just three minutes into the second half through Laia Balleste’s header from Natasha Andonova’s free-kick, but Koge restored their three-goal cushion in the 64th minute when Carusa headed into the top corner from Mille Gejl’s delivery.
Emelia Oskarsdottir’s low shot capped off a dominant display from the hosts as bottom side Servette slumped to another crushing defeat following their 8-0 loss to Lyon last week.
Naomie Feller scored twice as Paris Saint-Germain thumped OH Leuven 5-0 in the Women's Champions League.
Rasheedat Ajibade put PSG ahead in the ninth minute with a smart strike into the bottom corner and Feller extended their lead with a brace in 12 minutes after the break.
Feller turned provider for Sakina Karchaoui to slot past Lowiese Seynhaeve and Vitoria Yaya rolled the home from just inside the box to keep PSG unbeaten after two matches.
Inter Milan needed a last-gasp equaliser to salvage a 1-1 draw against Austria Vienna.
Vienna, making their debut in the competition this season, went ahead at Franz-Horr-Stadion through Modesta Uka’s stunning strike from distance, which dipped into the bottom corner.
Vienna looked set to clinch three points, but Ivana Andres Sanz had the final say in the third minute of time added on after the hosts were unable to clear from a corner and the Inter skipper fired home.
