Bayan Munich can win against Leverkusen but it is wrong to think that Bayan Munich will win every match against the teams you consider easy opponents. We often notice that in important matches big teams are defeated by relatively smaller teams or do not get full points in those matches. Bayern Munich should not plan all the matches at once, the match they play is important for them and they have to win that match. Leverkusen went undefeated last season to secure the title, but that doesn't mean they are stronger than Bayern Munich.
Leverkusen has looked a little different after winning the Bundesliga last season with an unbeaten record, but this season it is no longer the case because Leverkusen has lost when facing Leipzig in the second match at the beginning of this season. But in terms of strength, Leverkusen must still be considered a dangerous opponent by any team in the Bundesliga because Bayern Munich must not underestimate an opponent like Leverkusen, especially since Bayern Munich is also being led by a new coach this season.
Leverkusen's defeat last weekend I think does not need to be considered too much, they have played well but it's just that Leipzig was luckier and overall Leverkusen's performance is still quite good this season. Bayern is a team that wants to win the title again after last season their dominance was broken by Leverkusen while Leverkusen's position is currently the defending champion so of course the defending champion will still be favored and taken into account in the competition for the title and even in terms of possibility I think Leverkusen and Bayern have the same percentage.
