If you are going to start the same team and the same tactics that beat Bayern in their own stadium, you should have it easier against a weaker Arsenal defense. Especially if it's a do or die game.
Dortmund to win @3.31
Dortmund +0.25 @1.89
Over 2.5 @2.04
I demand to see Dortmund of last season again. Tonight.
Either way, it will be one hell of a game to watch.
