I will not be surprised if eventually Bayern Munich looses out on this seasons Bundesliga title but with leipzig, and Dortmund I do not have a particular, they both frequent the top four positions on the table often, it will be almost like a norm if it happens that both of them eventually finishes top four or even either of them but with the title Leverkusen even looks more viable than this other two for the title.
Does any team have a chance to stop Bayern Munich from winning the league this season? Even though the season hasn't started yet, based on the clubs performances in the preseason games, I don't think Bayern Munich will lose the Bundesliga. Any team can win the league, even though there isn't a weak team at right now, Dortmund and Leipzig are both capable of finishing in the top four, but Leipzig may struggle this season since they’ve sold several of their best players.
On the other hand, I do not believe Leverkusen has what it takes to defend the title this season. You believe in Leverkusen even though you are aware that Ten Hag is the new manager. The only team I'm hoping for to win the league again this season is Bayern Munich, the other teams are going to compete for the top four, and it would be very disappointing if Bayern Munich did not maintain their winning ways. The league starts tomorrow.

It's possible to stop Bayern Munich, Xabi Alonso exposed them, but I don't think any team can do that this season I'm not judging by the Pre-season matches though cause some clubs don't take it too seriously to avoid injuries ahead of the new season, I just have this strong feeling that Bayern Munich would still dominate their league this season.
Erik Ten Hag is the coach I would've said that would be capable of winning the league but after what he did at Manchester United I don't see that happening the only man capable is out and coaching Madrid thereby giving Bayern Munich more chances to win consecutively.
