The Gunners suffered their third defeat in five games at the hands of Manchester United at Old Trafford on Saturday, following losses to Norwich and Tuesday’s Bundesliga opponents.
Wenger’s side are second in their Champions League group behind the German outfit, and the Frenchman believes the north Londoners are still in a strong position to book their place in the last 16.
“[Our form] is a concern because we had a very promising start and of course we have gone through a difficult spell,” Wenger said.
“We want to respond to that and rectify that very quickly because it is not only the fact we lost the [Manchester United] game but the way we lost it.
“In terms of the group, the fact that we lost against Schalke means it is important that we win [in Germany] and finish the job well. We are still in a strong position in this group but of course we want to come out with a good result.”
And the Arsenal boss is looking for a response from his players following their 2-1 defeat by the Red Devils on Saturday.
“We have analysed it, watched it and spoken about it,” he said. “We know that we didn’t perform as well as expected.
“There is only one way to respond to that and that is to come out with a good performance tomorrow night.”
• The teams met in the 2001-02 group stage when the coaches were, as now, Arsène Wenger and Huub Stevens. Arsenal won 3-2 at home but lost 3-1 in Gelsenkirchen.
• Schalke have lost their last two home contests with English sides and not scored in three. They went down 2-0 to both Manchester United in the 2010-11 semi-final first leg and Manchester City in the 2008-09 Uefa Cup group stage. Their home record against English teams reads W3 D1 L2.
• Their win at Montpellier was only Arsenal’s third in 13 away matches in the competition proper, a run that includes eight defeats.
• Klaas-Jan Huntelaar and Thomas Vermaelen were team-mates at Ajax from January 2006 to January 2009.
