The attack power on Dortmund's front line is very weak
Borussia Dortmund is a very good team. This is a team that have transfer structure, they don't just spend on player that don't worth. Though right now the club is going through a rehebilation process . They brought in Sébastien Haller, who scored couples of goals for the team .
Moreover they have the like of Marco Reus who is an excellent player to the team so I see them going far in the German Bundesliga this season and also in the UEFA champions league. Possibly winning it.
