The scenario is like always the same in the recent years. Bayern Munich take the lead and win an easy championship. Dortmund follow them right behind and Leipzig - Freiburg - Leverkusen trio share the positions right below. This season is a little more different of course. Some teams are not having a good season.
Leverkusen started the season really horrible. They are still far away from the top positions now. Xabi Alonso's arrival has started to change something by the recent weeks though. They won their last three games. But their road is really full of obstacles until reaching top 4. I have big doubts about their making it there.
It's true, as you said, the scenario in the Bundesliga really hasn't changed at all, until now there hasn't been a single club that can surprise and take over Bayern Munich's place at the top of the standings. Bayern Munich have won the Bundesliga championship and lifted the Bundesliga trophy for ten seasons. successively, the trophies that have been collected by Bayern Munich are 32 trophies, I really hope that other teams are able to make changes and can get rid of Bayern Munich from the hunt for the Bundesliga title, like AC Milan got rid of Juventus.
