Schalke midfielder Lewis Holtby is confident that they can defeat Arsenal at the Emirates on Wednesday.
The German club will head into their clash with the Gunners in the Champions League second in Group B, two points behind the London outfit.
"It is the Champions League and we will try to win every match," he said. "I never have a negative approach going into a match, I did not have that against [Borussia] Dortmund either.
"To be honest, it is always a 50/50 chance and form on that day that decides which team win. We will strive for a win on Wednesday."
In the other Group B fixture on Wednesday, Montpellier will host Olympikcos in France.
