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.
I agree, Frankfurt will not be able to shock the world and they won't win anything. I agree that we have seen them do nice and all but that was it and I do not think that we are going to see anything further anytime soon, whatever happened has already happened and that was it, we are not going to get anything more from them.
In the end, we could consider how things could change and for that to mean something further we need to just see Frankfurt go on a huge winning streak, like if they can win ten games in a row, then yeah they could definitely go for a title and be above Bayern in that case. But, can you really see them do that? I do not see them do that at all, it just doesn't really feel like that at all, it is a totally different situation. I believe Frankfurt has the chance to finish second this season at best case, unless they go worse of course, and that would be good enough, I do not think that we are going to get anything further than that.
