Niederkorn had been looking invincible so far this season, but after going in to half time at 1-1 they were undone by two goals from Dave Turpel early in the second half at Dudelange. Striker Aleksandre Karapetian managed to grab a goal back on 67 minutes, but when Matias was dismissed for a second bookable offence on 75 minutes it was always going to be difficult for the visitors to find an equalizer and the match ended 3-2 for Dudelange.
Both teams now have 18 points from seven matches, though Dudelange have a better goal difference (plus 17 compared to plus 15 for Niederkorn). They are four points clear of third place FC Hamm Benfica, who beat Hostert 2-0 at home. Hamm, the surprise package of the season so far, moved above Jeunesse Esch who could only manage a 1-1 draw at home with Rodange. The other Esch teams faced each other, with Fola winning 1-0 at bottom club US Esch and moving in to fifth place in the league table.
Elsewhere Differdange beat Racing Union 2-1, Pétange beat Strassen 2-1 and Mondorf beat lowly Rosport 3-2.
