German club FC Schalke have upset Arsenal 2-0 at the Emirates Stadium in the Champions League tonight.

The Gunners produced absolutely nothing from an attacking sense with their first real effort of any notice coming in injury-time when Schalke keeper Lars Unnerstall kept out Santi Cazrola's effort.

Apart from that, Arsene Wenger's men supplied very little for their fans to get excited about as Huub Stevens' Schalke side proved to be much more effective when going forward with the likes of Ibrahim Afellay, Klaas-Jan Huntelaar, Jefferson Farfan and Atsuto Uchida providing plenty of problems for the home side.

The deadlock was broken when Huntelaar slotted home Afellay's headed cross from 10 yards in the 76th minute before the latter made it a two-goal lead with four minutes remaining when he swept home substitute Jermaine Jones' low pass.

Schalke had a penalty shout in the 13th minute when Vito Mannone appeared to have brought down Afellay in the area but the Dutchman actually received a yellow card for simulation.

The defeat was a very disappointing result for Arsenal, who lost to Norwich City on the weekend, and it was their first loss at the Emirates in the Champions League since 2009.

The result saw Schalke move to the top of the Group B table on seven points form three outings with the Gunners remaining second on four ahead of Olympiakos on three, who beat Montpellier 2-1 tonight, with the French sitting at the bottom.
