They have big ambitions to win the championship, but the problem of consistency in performance is still one of the obstacles that cannot be overcome. Frankfurt is currently in second place, they have managed to beat Leverkusen, Leipzig and Dortmund, but Bayern Munich is still very safe at the top of the standings with a 6 point advantage. It will be very difficult for Frankfurt to be a contender in the title race if they are not consistent in maintaining their performance because Bayern Munich are also very ambitious to win the title after their dominance collapsed last season.
Actually i want to see Leverkusen can being an strong contender with Bayern Munich for race title but unfortunately Leverkusen performance is decline compared to last season and about Frankfurt actually their manager Dino Toppmöller never targetting the championship because he has realize it's hard to compete with Bayern munich and although Frankfurt recent performance is very impressive but i highly doubt they can able to managed their consistency until ended of this season
I have to says for Bundesliga Bayern Munich is too consistent compared to other teams so they didn't gets decent opponent for the title and i know Frankfurt currently in the second place but i don't think they can able to taking over first place from Bayern Munich
