Bayern pre-matches result.
Bayern 2 - 1 Lyon
Bayern 4 - 0 Tottenham
To conclude, give Bundesliga title to them. I don't see any other club that can fight him for the title at this moment. If you ask me how much their chance to win the title, and i surely say they have 100% chance to win it. I know others may argue it's a pre-season, but don't forget massive result in pre-season represent how capable they are in winning the title.
Especially, we're talking about Bundesliga, not EPL.
As long as the Bundesliga is concerned Bayern Munich face no competition winning the league title. Bayer Leverkusen just had a one season wonder that made them champions and now Bayern are back at their best to continue their dominance in the Bundesliga, I see them winning and retaining the league title again next season.
