A draw is a pretty good step for Leverkusen so that it still adds points, even if it's only one point, rather than losing and not giving any points. It's not usual for Dortmund to be in the top five of the standings, because usually they also compete for first place. Meanwhile, Stuttgart is a new team that has entered the top three. This season's matches will be more exciting because there is no guarantee that Bayern Munich can win again this season because it looks like many people are fighting for first place at the top of the standings.
Bayer Leverkusen still stand top, despite facing a whole lot of difficult opponents, Xabi Alonso is cooking something for Leverkusen, can't wait to see them lifting the Bundesliga title. A draw points are for clubs that don't deserved winning and clearly fight for a draw. This was the moment for Borrusia Dortmund to win Bayer Leverkusen this season, they're suppose to be placed the first team to break the unbeaten run of Leverkusen this season. Dortmund messed their chances and allow Leverkusen to draw points with them, because they're in possession of the good qualities and odds of winning.
So, in the end it looks like the Bundesliga will have a new winner this season, although there is still plenty of opportunity for Bayern Munich to get better. But still, if at the same time that Bayer Leverkusen also manages to maintain this kind of good quality until the end of the season, then surely Bayer Leverkusen will not be overtaken.
But I think, something more interesting is about Stuttgart too and thus, the Bundesliga this season has a double surprise because apart from Bayer Leverkusen there is still a mediocre team is Stuttgart which at this moment has managed to have good quality too. At least, Bayer Leverkusen has shown extraordinary improvement from last season because they started from the relegation zone but regarding Stuttgart, last season Stuttgart did not have good results. Therefore, with Stuttgart being able to compete in the top four at this moment, of course a result like this is a big surprise in the Bundesliga this season and it seems that Bayern Munich is not ready to overcome difficult competition like this.
