They most likely don't have the experience to get them the league title so they are mostly just going to secure a very decent finish if they get he means to maintain his fome for which they currently thrive on, top contenders like Munich, Stuttgart and Leverkusen even if they aren't performing so we at the moment, they still have the experience that will help them get ahead if Frankfurt some time after mid season and towards the end of the season.
The experience of winning the title is very important for them so that they are always consistent in every match. Frankfurt has had a good season finishing the way they have even though their hopes of winning are far from expected.
The Bundesliga has many strong competing teams such as Munich, Stuttgart and Leverkusen, they also appear very aggressive, no one can determine the champion in the season, at least they have given their best and can move up the rankings in the Bundesliga standings.
I disagree if you say that the experience of winning the title is very important to be consistent, have you forgotten last season how Leverkusen managed to get their first title in the club's history. They had no experience of winning the title before but were able to perform consistently without losing until the end of the season, this could happen to Frankfurt. So don't underestimate a team that has never won the title. If they can play with passion and solidity they can definitely be consistent. I just want to clarify about the experience of winning the title.
But what is clear is that Frankfurt has been a very dangerous team, and what has happened to Frankfurt lately? How great their game is and now even players like Marmoush seem to be shining even more this year which makes the Bundesliga more competitive, much better and more interesting to watch. So far, Bayern Munich will still be the favorite to win the title, especially since the quality of Bayern Munich players is also even. However, even so, other teams like Frankfurt and Leverkusen can still give Bayern Munich a surprise until the end of the season.
