The hugely talented 22-year-old joined the side from IK Start until 2022 last week.
The former Inter Allies star impressed heavily on his debut despite losing 2-1 and outspoken Mjøndalen midfielder Christian Gauseth is surprised Ik Start allowed the highly-rated midfielder to leave for the fellow strugglers.
"I am shocked that Start sold him to us. We are in relegation, and then it is an advantage for us to bring in such a player." the 36-year-old said
IK Start are just a point above Mjøndalen in the relegation battle with the Ghanaian expected to steer them clear off the drop zone.
