London - Netherlands internationals Klaas-Jan Huntelaar and Ibrahim Afellay scored late goals as Schalke outclassed Arsenal to win 2-0 in the Champions League on Wednesday, lifting the team above the English side to the top of Group B.
The German visitors had wasted a string of good openings by the time Huntelaar put them in front with a low drive in the 76th minute, his ninth goal of the season for club and country.
Afellay clinched victory for Schalke in the 86th minute, slotting home from close range after Jefferson Farfan had evaded Arsenal's defence again down the right.
The loss ended Arsenal's perfect start to the competition and leaves manager Arsene Wenger with some worrying problems after being outclassed in every department.
Schalke are now on seven points - one ahead of Arsenal.
