Dortmund had a great chance to become champions last season, such a chance could not be missed, but they managed to lose the most important match. Now Bayer are 15 points ahead of them, and it will be impossible to reduce such a gap in the remaining matches, especially considering the form Bayer is in. But it is not yet clear whether Alonso will be able to maintain such momentum for Bayer, not everyone manages to go through the entire season at such a high level, and there will also be defeats.
Dortmund are out of contention for the title this season and I don't see any chances for them so far and when compared to last season, the Bundesliga has had a bit of progress from usual where some other teams have shown changes. Leverkusen are the strongest competitors so far and maybe they will try to maintain consistency in order to have a chance of becoming champion candidates. Our concern may be that in the remaining matches Leverkusen will not be able to maintain their victory due to injuries to several of their players.
If this happens it will be the same as Dortmund last season because in the end they had to give up the champions who were so close. Alonso needs to be aware of this condition because if his players are not rotated he is worried that they will experience fatigue.
