If you want to beat Bayern, then you need to end up with a better result as well, and you need to keep winning, the moment you have back to back bad weeks, Bayern will use that as advantage and put a gap between you. The gap is two games now, and I do not think that Bayern will have 2m ore bad games than Leipzig for the remainder of the season, which is proof that we are not going to end up with anyone but Bayern win the league this season.
We should not reach any conclusions so early. Because there is still a long way to go in this season and there is also a good enough time for any other team to actually catch up to them if Bayern Munich starts performing badly. And I do not think the whole season is going to go that smoothly for them, especially with the new coach. It is only a matter of time before some coach finds some weakness in their tactics. Something similar like what happened with Leverkusen in the last season. At least that's what I am thinking right now. But if they do not face any problems, then it's all good, and I think if the performance does not deteriorate for Bayern Munich, they are definitely going to win the league
