Dortmund and Leverkusen won't pose a serious threat to Bayern Munich this season, as neither team is yet on par with Bayern Munich in terms of strength. However, if we look at the details, Dortmund might be better than Leverkusen this season, although Dortmund won't be able to break Bayern Munich's dominance this season, as Munich remains quite solid with the depth of their squad. I wouldn't expect anything less from Leverkusen or Dortmund this season, as Munich will never neglect any opportunity to win this season.
We hope that there is competition that adorns the Bundesliga this season so that it will be much more interesting when following it even if you see the quality of the two teams it is not comparable to the players owned by Bayern Munich. Pressing for Bayern Munich may be easy but what is difficult for the two teams can appear consistent until the end of the season because later they will face the injury of players in competition so that it is difficult for Leverkusen and Dortmund to continue to be consistent.
