Ajara Nchout registered her first goal for Valerenga in their 1-0 win over Stabaek in Sunday's Norwegian Toppserien encounter at Intility Arena.
The 26-year-old, who joined Monica Knudsen's ladies from league rivals Sandviken last December, made an instant impact on her league debut as her second-half effort turned out the winner.
After a 0-0 first half draw, the Cameroon international broke the deadlock in the 59th minute for what stood as the winner for the hosts.
Match-winner Nchout was in action for 71 minutes on her debut before she was replaced by Celin Ildhusoy.
