I'm not surprised by this result, as Leipzig didn't build a much better team for this season, so it was a given that Bayern Munich would win easily, especially since they were playing at home. As we know, Bayern Munich's character is always to be productive when their opponent is slow, and they proved that again in this match.
Bayern Munich's strength like this will be very difficult for any team in the Bundesliga to overcome. Looking at the entire team, perhaps only Dortmund or Leverkusen can put them under some pressure this season. However, if those two teams suffer the same fate as Leipzig, the title race will certainly not be as exciting. Leipzig may not have built a team by bringing in a number of potential players this season, but considering their performance last season, Leipzig shouldn't have suffered such a crushing defeat.
When the new German Bundesliga season hadn't started, we had been anticipating that Bayern Munich would win this season's Bundesliga title easily because they have no serious rival, so the performance of other clubs in the Bundesliga yesterday proved that Bayern Munich truly has no rival this season. I don't see Bayer Leverkusen and Borussia Dortmund as clubs that can rival Bayern Munich for the Bundesliga title this season, and I won't be surprised when they fail to compete for the Bundesliga title this season.
