The only goal of the match came in the 40th minute after a corner from the right.
After Norrköping had failed to get the ball away, it finally reached Jeppe Okkels who slammed 1-0 into the net.
Elfsborg was a bit sharper throughout the match, especially in the first half where the home team had several good positions.
- We are not happy with the first half.
We do not get it right and everyone probably sees it, says Norrköping's coach Rikard Norling to Discovery +.
- It continues decently in the other as well, or throughout the match.
It is only to state that we are not at our own edge.
Stylish pair of legs by Rönning
With 25 minutes left, goal scorer Okkels got a chance to extend the lead.
But the Dane did not really reach the pass which, if it went ahead, would in all probability have resulted in a 2-0 goal.
Norrköping had a hard time on the waterlogged pitch - his trademark technique was nowhere in sight today.
Khazeni came forward centrally and pulled away a hard shot against Tim Rönning in Elfsborg's goal.
Rönning made a nice pair of legs and made sure that the home team's zero remained intact.
Elfsborg won 1-0 and with the victory is a new table four - seven points behind league-leading Malmö.
- This was nice after two straight losses.
Three points was the most important thing, says Joseph Okumu.
