Brøndby moved clear at the summit of the Danish Superliga after a narrow 3-2 victory over Sønderjyske in the fourth round of the season.
Mads Frøkjær scored twice for the home side, while Olti Hyseni added a third just two weeks after joining Brøndby from Sønderjyske. The result leaves head coach Thomas Nørgaard's side on 10 points from four matches, one ahead of Copenhagen, who have nine points from three games, and three clear of Midtjylland on seven, also with a match in hand.
The defeat leaves Sønderjyske bottom of the table with just one point and no wins after four rounds.
