I no longer even consider all of these teams to be a threat to Leverkusen because Leverkusen's biggest threat this season is Bayern Munich and that team has also been defeated by Leverkusen this season. So I no longer consider all the teams you mentioned to be a serious threat to Leverkusen so it could be quite possible for Leverkusen to continue this unbeaten streak until the end of the season even though it is also possible for Leverkusen to get a draw in the remaining nine matches.
There are no more obstacles that Leverkusen will face after successfully overcoming Bayern Munich as one of its strongest competitors. The championship title almost belongs to Bayer Leverkusen and it will be a new history for the club if they succeed in winning the Bundesliga this season, while Bayern Munich's dominance in the last 11 seasons will end this season. Leverkusen is trying to carve out a great record with Xabi Alonso, apart from wanting to win trophies, they are also trying to become an unbeatable team in the Bundesliga.
