Interesting match today between Dortmund and Gladbach. With Leipzeg losing Werner, I suspect these two would be the closest to challenging Bayern.
Gladbach have a young team whose players should only improve.
If we're being honest, Bayern have been looking so strong and consistent that it would need fatigue or injuries to wear them down if another team truly wants to challenge them. I think on paper Dortmund are the only team who can do it, in terms of depth they might actually be a bit ahead of Bayern. Leipzig should drop off for losing Werner and Schick, but because of Nagelsmann and how well he managed such situations at Hoffenheim, I'd give them some outside chance to get to something like 80 points. Leverkusen need to sign a couple of players before we can take them seriously again. Gladbach don't have the depth to challenge for the title, especially not with the extra packed schedule we got this season and them playing CL for the first time in a couple of years, they can beat Dortmund today and as last season showed even Bayern, but over the course of 34 games they will drop points every know and then that Bayern or Dortmund won't.
