They are far superior to every team in the league, and that's why this league isn't competitive and somewhat boring. The outcome of most games involving Bayern is predictable.
I'd say the EPL and even La Liga are superior this season, in terms of excitement and the unpredictability factor. At least there are a few teams competing for the title. Even Serie A has a strong and consistent Roma pushing Juve all the way. No one is even remotely challenging Bayern.
