Borussia Dortmund has 3-3-0 in their last 6 games, but the last victory against their rivals Bayern Munich was extremly strong. They crushed Bayern 1-3 and totally outplayed the last years Champions League finalists.
FC Koln is a typical home team who can surprise at home witch they have showed against Bayern Munich. Koln has won 4 straight home games in the league, but has only 0-2-2 in their last 4 matches away from home.
Borussia Dortmund has fantastic offensive players like Barrios, Sahin, Bender, Großkreutz and Götze but they also have a very good defense, with a very rough 22-year old center back, Neven Subotic.
Neven Subotic has got 7 yellow cards and 1 red card in 22 games this season. He is alot like Nemanja Vidic at Manchester United in his way of playing, rough and solid, but Subotic is much more unstable and got more to learn.
Even if Koln is bad away from home, they still got offensive powers in Novakovic (9 goals in 18 games) and Lukas Podolski (10 goals in 23 games) and Subotic will definetly have to stop these guys.
4.50@Unibet on that Subotic will receive a yellow or red card in tonights match is way to high, and worth some units.
