The Bundesliga outfit require three points from their Champions League Group F meeting with the Gunners at Emirates Stadium tomorrow and Owomoyela says they are coming with confidence in a bid to keep their run in the competition alive.
"The knowledge that a win over Arsenal keeps our chances of having a decisive game against Marseille on matchday six alive is a big motivation," Owomoyela said to Goal.com.
"We are not the kind of team that budges under pressure. We are a young team and are always positive. We are hungry for success.
"We are travelling to London with the aim of winning. We are not thinking about Champions League elimination."
Dortmund sit third in the group with four points and are in desperate need of a win to keep their hopes of finishing in the top two alive.
