I'm still not convinced that Bayern Leverkusen will lose points in the remaining Bundesliga matches. Bayern Munich is the only club I see that can pose a significant challenge by failing to secure all three points in a match. Some other clubs may want to give them a difficult time, but losing to them is not something I believe is even possible. The schedule should allow them to take a comfortable lead and win all three points in each game. Until then, let's see how they play out until the season's final match.
Bayer Leverkusen are the best team this season, they're doing their possible best to maintain the unbeaten run this season. With their current form, I would it call it luck because they're now finding it difficult to play tough opponents, with their watch back passed and doing everything possible to win matches, I no longer believed in Bayer Leverkusen and their losing day keeps drawing closer this season. Xabi Alonso will strengthen the positions and finds out spots that he thinks will be disturbing to him and find a way to fixed them within time for the purpose to set good running game.
In some circumstances, they seem to have had luck because their performance didn't look that good but managed to maintain an unbeaten record, such as when facing Koln, it was helped by the red card received by Koln players, also when they had difficulty winning in the European league, even in the second match against Qarabag, they almost knocked out but were lucky enough to catch up and even ensure they advanced to the quarter-finals without having to go through extra time, but their apparent luck can also be offset by hard work, the Bayer Leverkusen players didn't stop trying until the final minutes of the match and all their hard work paid off.
Maintaining their performance is not easy, but it is quite certain that they will become Bundesliga champions, even though their unbeaten record will be broken, but they have enough points so Bayern Munich hard to catch them, so bad results will not affect their standings until the end of the season.
