While the home side are yet to find their feet this term, the visitors have made a flying start, and will now seek to keep the juggernaut rolling.
Match preview
Copenhagen saw their 100% record come to a somewhat disappointing end last time out following a 1-1 stalemate against Randers in Sunday's meeting at the Parken Stadium.
Having picked up seven points from three league games so far, Jacob Neestrup's men are currently fifth in the Danish Superliga table, one of five teams with an unbeaten start to the new campaign
De Byens Hold have carried over their impressive domestic form to the European scene and are 90 minutes away from securing a place in the Conference League playoffs, after claiming a narrow first-leg advantage over Czech Republic outfit Ostrava on Wednesday.
While Copenhagen will have one eye on completing the job in next week's return leg, the immediate focus will be on this weekend's game on enemy territory, where they are unbeaten in eight of the last nine matches.
With a third title in four years the major goal this term for the visitors who relinquished their crown to Midtjylland last time out, anything less than all three points on Sunday would be deemed less than ideal.
Sonderjyske saw their poor start to the season hit a new low as they were on the receiving end of a 4-0 thrashing against Aarhus in Friday's meeting between the teams at Ceres Park.
That was a second defeat in three Danish Superliga matches for Thomas Norgaard's men either side of a 1-1 stalemate against Lyngby, which yielded their solitary point to date.
As a result, Sonderjsyke currently sit bottom but one in the standings with the league's joint-worst attacking record—just one goal scored—while only two teams have seen their defences breached on more occasions.
The early struggles for Sunday's hosts are unsurprising given their form to end the last campaign, where they failed to win any of their final three games, before going four matches without a victory in pre-season.

Team News
Highly-rated teenager Roony Bardghji is still facing an extended spell on the sidelines due to a knee problem, ruling him out of contention for Copenhagen.
Denmark duo Nicolai Boilesen and Andreas Cornelius will both not play any part here, but the latter is drawing increasingly closer to a return to action.
Victor Froholdt will be aiming to deliver the goods once again having found the back of the net in three of his last four matches for the home side.
Hamza Akman is yet to fully recuperate from a long-term injury problem, making the Turk a guaranteed absentee for Sonderjyske this weekend.
Gideon Duru featured once in pre-season for the away side but still awaits his official debut since joining from Rivers United during the summer window.
Sonderjyske possible starting lineup:
Flo; Vinderslev, Sommer, Soulas; Barkarson, Bjorklund, Cherif, Emini, Oggesen; Gallegos, Ingason
Copenhagen possible starting lineup:
Trott; Huescas, Diks, Garananga, Meling; Mattsson, Falk; Larsson, Delaney, Elyounoussi; Oskarsson
We say: Sonderjyske 0-3 Copenhagen
Sonderjyske could really do with a positive result this weekend, but Copenhagen will have other ideas as they look to heap more misery on the home side.
