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.
Bayern Munich took precautions they saw their mistake and amended it, so I don't think they are ready to lose out again so soon from the trophy they just reclaimed. Besides, the thing is that, as it stands there's no team that can rival Bayern Munich in the league as of now.
