PSV - Dortmund matchup could also be evaluated as one of the close matchups. Because PSV aren't a weak team and can't be underestimated. Especially by Dortmund I mean. Dortmund have had a really good run in the Champions League so far. I must admit that. However they are still inconsistent in general when we add their performance in the Bundesliga into account as well.
If they can't make any progress until their Champions League first leg game I don't know what kind of a Dortmund we would watch on the pitch against PSV. But as long as they don't lose their focus on the Champions League they should still be able to stay one step ahead.

To be honest, I don’t even know who in this pair the bookmakers will consider the favorite - probably Dortmund? Dortmund won the group of death, but in the Bundesliga they are in 5th place (having lost their chances for the title a long time ago) and their winning percentage is below 50%. PSV have 16 wins out of 16 in the national championship (wow) and their mentality is clearly closer to the championship. Maybe in this pair it is worth betting on PSV (if they are underdogs).
