The point difference between Bayern Munich and Dortmund is just 1 and this doesn’t mean Dortmund will take Bayern Munich position. Bayern Munich is an experience team in winning Bundesliga and I don't think right now Dortmund can go with championship. Bayern Munich is in their worst state of performance but won't miss opportunity of winning Bundesliga after losing champions league, Bundesliga is very important for them to win.
Even though Bayern Munich has a long history of dominance in the Bundesliga it is crucial to keep in mind that every season is unique. Dortmund is a force to be reckoned with this season as evidenced by the fact that they are presently only one point behind Bayern. Bayern has been having trouble lately but that does not mean they can not get things back on track. Dortmund could however, build on their recent success and triumph if they continue in that direction. In sports anything can happen at the end of the day, thus it is hard to forecast the result with certainty. It will be interesting to see how the rest of the season develops and which club wins the title.
The point difference between Dortmund and Bayern Munich is only one point. If we only look and think that Bayern Munich will win the championship because they have been at the top of the standings for a long time, it is not necessarily true because there is Dortmund who consistently wins every match, with the evidence of being only one point behind to overtake Bayern Munich at the top position.
