It is the truth that Dortmund's front line isn't as strong as Bayern Munich considering a possible title race. Especially thanks to the addition of Kane to the team Bayern Munich are far stronger in the attacking line than all the remaining teams in the Bundesliga. On the other hand Dortmund have added Füllkrug to their squad right before the transfer window ended.

This transfer should make their attacking line more credible at least. Because as you can remember Füllkrug was the top scorer of the league last season.

Considering this I think Dortmund can at least improve their results by the upcoming matches and be good enough to fight for second place in the standings.
