Preview: Arsenal vs. Borussia Dortmund

Arsenal will attempt to continue their 100% start in this season's Champions League tomorrow night, but face a stern test of their European credentials against last campaign's beaten finalists Borussia Dortmund.

The Gunners have gone 12 games unbeaten in all competitions that include an impressive 2-0 win over Napoli in their last Champions League fixture.

Arsene Wenger's side will be without midfield anchorman Mathieu Flamini for the clash, as he sustained a concussion in Saturday's 4-1 win over Norwich City at the Emirates Stadium.

Aaron Ramsey should come in for Flamini after an impressive performance as a substitute against Norwich, with Jack Wilshere, Mesut Ozil and Santi Cazorla continuing behind Olivier Giroud.

Dortmund have a whole host of first-team regulars absent ahead of their trip to North London including Ilkay Gundogan, but Nuri Sahin and Marcel Schmelzer are expected to pass fitness tests.

Jurgen Klopp will sit out the second game of his two-match touchline ban, as Dortmund look to gain ground in Group F.
