Dortmund are obviously not in a very fine form this season as stats show they are eleven points behind table leaders Bayern Munich. Against Bayern Leverkusen at home, Dortmund have upper hand playing at home though Leverkusen are a really strong opponent who currently sit second place in the table. It will take some kind of outstanding performance to beat Leverkusen on Friday.
Dortmund's performance this season has been quite erratic. This team is not able to fight for the title. Even qualifying for the Champions League is very difficult for Dortmund. Dortmund is currently in sixth place in the points table. Dortmund has won two of the last 5 matches and drawn three matches.
Leverkusen failed to perform well at the beginning of this season. As a result, Leverkusen was far behind in the points table. However, Leverkusen is in great shape at the moment. I don't remember the last time I saw Leverkusen lose.
However, Dortmund cannot be considered a weak team. At the same time, this is Dortmund's home match. So even though Leverkusen is in a strong position, it is difficult for Leverkusen to defeat Dortmund. A few days ago, we saw that Dortmund was able to get 1 point against Bayern Munich. If Leverkusen wants to earn 3 points, they will have to dominate from the start of the match.
