Borussia Dortmund vs Arsenal: Preview and predicted Gunners lineup
However, Arsene Wenger's men bounced back spectacularly against the inform Liverpool on Sunday with a 2-0 win. Dortmund on Wednesday night and Manchester United on Sunday still represent massive tests for Arsenal. They will be making the trip to Germany without a number of key players like Jack Wilshere.
This game comes a little too soon for Walcott, but Arsenal appear to have enough strength in depth to name a strong team.
Dortmund and Arsenal have faced each other at the Westfalenstadion in the past with the English club unsuccessful on the two occasions. In fact, Westfalenstadion has been something of a fortress for Dortmund, as they have had some straight victories since the 2011 defeat against Marseille.
Arsenal have been doing well of late away from home in the Champions League. They have won the last three matches and should be quietly confident about getting at least a draw. Three teams in the group are locked on six points. It will come down to taking the home advantage and Arsenal will be keen to prevent Dortmund from doing so.
Arsenal predicted squad: Szczesny, Sagna, Mertesacker, Koscielny, Gibbs, Arteta, Ramsey, Cazorla, Ozil, Rosicky and Giroud.
