Leverkusen have not been in good form this season. And we saw it in their performances in the first two matches. Leverkusen won despite not performing well against Gladbach. On the other hand, the team lost against Leipzig. As the team aims to win the Bundesliga title, Leverkusen cannot secure the title if they cannot continue their winning streak. Either way the team will try to get 3 points against Hoffenheim.
Leverkusen have won four of their last five matches against Hoffenheim. This group is not very strong. So if Leverkusen performs a little carefully, and if the defense is a little strong, then Leverkusen will be able to get 3 points from this match. However, Leverkusen's defenders must play well.
I think it's too early to say that Leverkusen are in bad form at the start of the season just because they lost against Leipzig last weekend, it can't be used as a reference because overall Leverkusen have played well, it's just that they were a little unlucky to have to admit their first defeat of the season so quickly.
Xabi Alonso is a coach who has been quite successful in building or improving the performance of the Leverkusen team since his arrival, so that will also apply this season.
There's no need to worry about anything and don't be too quick to judge the strength of the Leverkusen team, it's still too early.
