Wenger seeks European response
Manager Arsene Wenger hopes Arsenal will produce a positive response after slumping to a 1-0 defeat at Norwich.
The Gunners never really got going against a side which had leaked goals in recent weeks but stepped up their performance to record a first Premier League win under Chris Hughton.
Wenger knows Arsenal need to produce a much-improved display when they take on Schalke aiming to secure a place in the last 16 of the Champions League.
"I hope it will have a positive impact," Wenger said. "It was a shock to the system, but you have to give credit to Norwich because they played well, were completely committed and they deserved the win.
"Maybe we underrated the difficulty we would face, but the Premier League is the Premier League - if you are not ready for the fight then you will always have bad surprises.
"There is a big difference between the amount of possession we had and the amount of chances we created, that is down to the fact that Norwich defended well and we did not create a lot."
