But Bayern managed to take the first place last season. Yes, Dortmund got the same number of points, but Bayern scored more goals and eventually won the Bundesliga. This kind of competition between Dortmund and Bayern happens regularly, so I wouldn't say Bayern are in some kind of crisis. It's just that this season has been difficult for all clubs.
Virtually talking, Dortmund get the Bundesliga title and throw it to Bayern Munich at the last moment for no reason.
It is true on paper Bayern Munich added another trophy to theirs but they should not consider that as an achievement. They should regret playing that way in the previous season and they are doing their best to rebuild the squad. They are seeking now Harry Kane to close the gap in their attack line and Kyle Walker to consolidate the defensive line.
