This season things are very different from last season, Leverkusen are not the same invincible team they were last season, to see they are not the same team they were last season:
Leverkusen played
2 games,
won only 1,
conceded 5 goals,
scored 5 goals. The problem with that is that Leverkusen didn't play against very strong teams, although Leipzig is a good team, they are not candidates for the title, that's why I don't consider Leipzig to be a very strong team, they are strong, but not very strong. So conceding 5 goals in just 2 games is a huge disaster, it's hard for a team to win a league with a very weak defense like Leverkusen's, but
Bayern played
2 games,
won 2,
conceded only 2 goals,
scored 5 goals. It clearly shows that Bayern will be champions this season, and they will beat Leverkusen when they face each other.
There will always be changes every season, be it for the better or for the worse, even consistent teams will experience this, it's just a little change that they experience. We can't always expect the same appearance from a team every season, especially if it's without a defeat, it's clearly something that is very difficult and can even be said to be something impossible to do again.
Now Bayern Munich is preparing to reclaim what they lost last season, honestly I believe Bayern Munich will win the title again than I believe in Leverkusen who can maintain an unbeaten record. because in my opinion it is twice as difficult when compared to Bayern Munich who are used to being champions in the Bundesliga. This is just a realistic view.
