FC Copenhagen came from a goal behind to defeat Odense BK 3-1 and move seven points clear at the top of the Superligaen.
The defending champions had trailed to a 35th-minute goal from Rasmus Falk Jensen, but Solvi Ottesen equalised on the stroke of half-time before Cesar Santin's double turned the result in their favour.
Second-placed FC Nordsjaelland lost ground on the leaders with a 1-0 defeat at home by Lyngby, who snatched the points eight minutes from time with a goal from Jonas Henriksen.
AGF are just one point behind the top two following a 2-0 victory at home to Koge. Soren Larsen scored both goals for the winners after 31 and 60 minutes.
Brondby's poor start to the season continued with a 1-1 draw against AaB. Mikkel Thygesen's 53rd-minute strike cancelled out Lasse Nielsen's first-half opener for the visitors, but the result leaves Brondby in the bottom three.
