Frankfurt will be part of the challengers and maybe they cannot be underestimated because like the previous season where Leverkusen was able to provide a very extraordinary surprise for Bayern Munich. Although if you look at Frankfurt it is different from the results obtained by Leverkusen in the previous season and also talking about consistency in the match. If Bayern Munich does not create a slightly greater distance then it is not impossible that Frankfurt will try to catch up on the points and that can still be done when they play more consistently.
Catching up on the six points already owned by Bayern Munich is not easy for Frankfurt if Bayern Munich is still strong enough to dominate the Bundesliga this season. Moreover, if Frankfurt itself does not have the power to surpass the strength of Bayern Munich so that it will also be a very real obstacle for Frankfurt and even Frankfurt's position itself is still likely to be taken by Leverkusen if Frankfurt's consistency does not continue to increase in the upcoming matches.
6 points is not an easy distance to catch up, but it is not impossible to do as long as they can continue to get full points and they need Bayern Munich to stumble a little. They will still meet and in their meeting Frankfurt should be able to take advantage of that to beat Bayern Munich. However, this is clearly not easy to do, because beating a team like Bayern Munich must have a hard work and sometimes also requires a little luck to do that. With Leverkusen's success last season, that could be a motivation for them.
