Bayern Munich is obviously going to be the winner of the league title every season because they have almost no competition in the league. Dortmund is the only competition that can be considered, but it is not a very credible competition since they are not at the same level as Bayern Munich. And Dortmund is not a team that chases after trophies, they are just a team for business purposes. Leipzig is also not a viable competitor. So as long as nothing terrible happens to Bayern Munich, I don't think they will be dethroned from the league title.
Borussia Dortmund is 50% weaker than last season in my opinion, they sold their main player and I highly doubt they will be able to recover so soon, on the other side we have Bayern Munich that brought in the sadio mane and managed to keep their main scorer goals for another season, this way Bayern Munich is stronger than last season and with that it has more than 80% of being champions once again, I think there is no doubt about that. I believe that the big question that the management of Bayern Munich should be concerned with is if with this team they have enough strength to win the champions league, this is the only big challenge for Bayern Munich, the bundesliga is no longer a big challenge for Bayern Munich, they win so easily that I doubt they worry too much about making an effort to win.
The World Cup process can really affect the teams deeply. Because the fixtures are going to be way different than normal.
wait, won't the local leagues stop while the world cup takes place?
