Leverkusen is indeed a good club and its performance is quite convincing this season. but it is true what you say if Bayern is actually still above Leverkusen regarding the ability of its players. In the last match which ended in a draw, Bayern actually had a 2-1 lead. However, it was very unfortunate that at the end of injury time, they made a mistake and were very unlucky. So Leverkusen got the final kick which made it a goal.
I Think Leverkusen recent success, it is obvious that they have not yet reached Bayern Munich level. Munich stands out due to their consistent dominance in the Bundesliga and strong player pool. Leverkusen is improving, but more work needs to be done before they can threaten Munich dominance. Leverkusen has made improvement, though, and with more perseverance and consistency, they may someday be considered serious competitors. Bayern Munich continues to dominate the Bundesliga for the time being.
