]Yeah, despite the level of performance Leverkusen pulled off last season winning the bundesliga trophy without losing a single league match, still, they don't match in comparison with Bayern Munich who have won the bundesliga back to back, whereas Leverkusen by way of their drop in form this season doesn't seem like they could pull such show because right now they're sitting 7 points beneath Bayern Munich and am convinced Munich isn't dropping points for Leverkusen to close in on them.

We should understand that for a team like Leverkusen, that's still a lot to see them in the top side of the Bundesliga. Before Xabi Alonso joined Leverkusen, they were a normal team and they couldn't think about winning the Bundesliga title while now, thanks to Alonso they have a much better performance.
I think the performance of Leverkusen was still not that bad and they can still think bout being in a better position on the table during this season since there is a long way ahead until the end of the season.
The tremendous transformation of Bayer Leverkusen from the stables of a regular level team in the bundlesliga league table and Europe at large to a now well competitive team for titles since Xabi Alonso took over the club is amazing and spot on. However, they can only have to battle for a spot in the top four of the table this season, probably finishing at 2nd or 3rd position as I don't see them winning the bundesliga title this time because the grandmaster Bayern Munich seem to have retaken it's regular position. But for a team like Leverkusen, finishing within the top four is no bad especially now they're playing in the champions league, except that fans has placed high expectations on them this season due to their amazing performance of previous year.
