For me I feel Frankfurt can't really meet up with the title race although this season they have really tried but it's not going to be easy for Frankfurt to met because for a team to actually be strong contestant of the league consistency must be one of the various factors which they must have and this was how Bayer Leverkusen were able to win the league last season as they were very consistent with their game play.
In fact, this season, Frankfurt's performance is much better and more consistent than previous seasons. They have only lost 2 times, and if you look at the number of goals, they have scored 33 goals so far, superior to Leverkusen. and in 5 matches, they won 4 times and drew 1 time. Actually, statistically, their performance in the Bundesliga is quite good and consistent.
However, if it is related to the Bundesliga title race, indeed, it is still difficult for Frankfurt to be like Leverkusen who was able to surpass other clubs last season, it will be quite difficult. Moreover, currently, Leverkusen and Leipzig are also quite aggressive in achieving a higher position, so the competition is still quite tight. And most important again, as you said, Bayern Munich will still remain at the top, and the probability until the end of this season is higher.
