Yes. It is unthinkable that Bayern Munich, who have been impressive this season, finally suffered their first defeat this season against Mainz in a surprising way. This defeat made Bayern Munich's hopes of matching Leverkusen's unbeaten record last season finally disappear. Indeed, this defeat did not change Bayern Munich's ranking in the standings, they remain solid at the top, but this defeat should be a self-reflection for Kompany to be more serious in strengthening the defense line.
The facts is that Bayern Munich are know more maintain there performance anymore, that’s why they received a terrible defeat against the team that nobody can believe they’ve capacity of defeated Bayern Munich; but indeed with there much efforts they it possible by won the 2-1: which was very disappointed from them.
The way Bayern suffered a lot in the hand of the Mainz that are not strong enough, if they face a strong team in their next match i don’t think they can able to remain in their currently position which is top of the table; because I can see that their only ahead of Leverkusen with just 4 points.
I think this defeat was good for Bayern Munich because the desire to set a new record was stressing the team. It is good for the team to believe that they will win constantly, but a team also needs to lose in order to see their shortcomings. This defeat does not create a big problem for Bayern Munich and I think this defeat will reflect positively on the team.
It is an advantage for every team to know their shortcomings in advance. Munich also saw their shortcomings with this defeat. They may suffer more defeats, but I think the lessons they will learn from these defeats will contribute to the team.
The last time I checked football it is all about win, lose and draw. It is fine that you have more wins, less number of draws and if possible lesser number of losses. By this you could aim to win a title or trophy by the end of the season. No team goes to a particular season and decides to play unbeaten throughout the season. It only happens in a rare conditions.
With the present situation of the Bundesliga, it will become very much impossible for a team to play unbeaten throughout the season. This is because, it is no longer a league that is dominated by Bayern Munich. Look very closely behind Bayern Munich you will see Bayern Leverkusen and Frankfurt, so if Bayern Munich makes mistake in only two matches they are out of the top. This shows how competitive the Bundesliga has become and we do not expect Bayern Munich to have 100% record
