Leverkusen are favorites against Gladbach. But Gladbach is a team that always performs well against renowned teams. We have seen many times in the past that Gladbach teams have beaten strong teams like Bayern Munich. So, although Leverkusen team is considered as favorite in this match, they will make a big mistake if they think Gladbach team is weak. Leverkusen's players will have to play the entire match very carefully if they want to beat Gladbach.
For more details, let's look at the H2H of both. Here Leverkusen dominates a lot with many positive results achieved and they have never tasted defeat in the last five matches against Gladbach. It's just that there were two draws that made both teams look equally strong and I think Leverkusen will still be able to win without any problems.
Even though Gladbach is the host, it is not difficult for Leverkusen to extend their away winning record and I think they have no reason not to steal full points in this early match. One thing is for sure, if Leverkusen loses or draws then Bayern Munich will lead the standings and that is not what Xabi Alonso wants. So it is only natural that Leverkusen will not let Gladbach put pressure on them.
