The club that's been a treat to Bayern Munich over the years and even supposed to be the league champions is Dortmund but they were very unfortunate last season and had sold their good players that would've helped them challenge Bayern Munich over the years.
Edin terzic is a good coach who I believe can still do something great with his team regardless of the fact that some good players were sold out already during the transfer windows, nevertheless we still have the likes of Donyell Malen a very good player with an excellent player statistic, if positioned well with good assit he can help the team a long way, he has two goals already.
Bayern Munich I believe will still have a beautiful finish this season as they have always done over the years, they stand to be the giant of the bundesliga as they have won the league title severally and we don't expect anything less from them this season although they didn't have a very good start but I still trust and believe in them, one thing that is usually epic about their games is the number of goals.
Although in recent times they have not really been epic with the number of goals they score in a match I still believe Bayern Munich will do good but if Dortmund brace up and further improvement on their tactics I think they still have the chances of being a good contender to Bayern Munich and be at the top, so I will say let's not rule out Dortmund yet there's still enough room for improvement and possibilities.
