It won't be easy for Leverkusen and I'm sure they won't be able to do it again this season because Bayern's team has improved quite a bit so it will be a threat for Leverkusen.
And also this week Leverkusen will face a tough opponent, RB Leipzig is a team that is difficult to beat so I think at the beginning of this season we don't need to exaggerate or measure Leverkusen's strength like last season, I'm sure there will be a difference compared to last season for Leverkusen and also other Bundesliga teams.
Against RB Leipzig this week I think Leverkusen's percentage to win is not that big.
Bayer Leverkusen appeared to be one of the top clubs that's promising for the the Bundesliga title this season. This is really going to be an amazing season for Bayer Leverkusen but following the desperate formidable form of other clubs, there chances of winning the league title have been compromised. However there's no need to panic because Xabi Alonso will reinforced his squad with tactical changes that would be helpful for the club. This season is completely different and there's plenty opportunities to be given for these elite clubs including the average clubs.
