We have to accept the reality that Leverkusen are not winning the Bundeslisga for two consecutive seasons,
Can you just tell me what reality it is you are talking about? If you can see the future please prove it to us and provide us more information.

They had a great performance last season. They scored some very important last minute goals in some games. So, they were actually as lucky as they were very good last season. I have no doubt that they will be very good again this season, but I don't think they will have the same luck. Indeed, their 35-game unbeaten streak came to an end against Leipzig in the league. I think we will witness a better rivalry this season. Both Bayer Leverkusen and Bayer Munich will be more predictable teams...
Of course last season was a very surprising season for Bundesliga fans, we have seen how the greatness of the middle team at that time showed its best quality by dominating the league without experiencing a single defeat, and honestly I will say again that it was a surprising performance from a team that was originally ordinary.
Last season most of us predicted that this season would definitely be more interesting to watch because the competition would definitely be even fiercer and I also don't know whether Leverkusen will be able to repeat the success like when they were last season or not,
but what is certain is that to return to setting an unbeaten record throughout the match I think for now it is very unlikely, but for the title problem at the end of the season it is still possible for them to get it again, and I am quite curious about what Bayern Munich will do after failing to defend the title last season.
