In my opinion, it is too early if we judge that only the two top ranked teams at the moment will win the Bundesliga, because the league has only been running for 11 matches, meaning that not even half of the season has been underway, in my opinion there are teams below them that could still move up to the top rank to win the league. This season, including Borrussia dortmund, which is only ranked 5th, currently there is a chance, even though they have only got 21 points, they are 10 points behind Bayer Leverkusen, who have 31 points, the possibility is not too small for them because this is only the start of the season.
Yeah it may look like it's too early to judge and all they but then one thing is sure and that's the fact that these two top teams are not looking like they are in any way loosing their form soon, they keep getting even better by each matches they play, so all they need at the moment would be consistency.
It will take Dortmund to win four matches in a row and for Leverkusen bro aswell loose four matches in a row before Dortmund will two points ahead of Leverkusen and the odds that this happens is almost zero considering the current form Leverkusen has, so it's still important to know that inasmuch as it's looking like there's still time, the big teams keep piling up points which will eventually make it more difficult for the smaller team to probably win and meet up, so even if the big teams have a slow down at any point they can still come back and stand tall again because they have the points advantage.
