Looking at the statistics of the match, I think it was a match where Borussia Dortmund should be happy with the 1 point they got. They had a very tough match and Bayer Leverkusen wore them out a lot. They are unlucky not to beat because they created a lot of chances. At least they were not defeated, so we have to think like that. Bayern will be the happiest with this loss.
I think Borussia Dortmund avoided a major setback against Bayer Leverkusen. Dortmund's draw feels lucky given Leverkusen's domination. Leverkusen played well, especially at home, but came up short. Leverkusen will regret missing a good opportunity to win all three points. However, Dortmund's resilience under siege is impressive. They've shown resilience previously, notably against Newcastle. Dortmund deserves praise for drawing a tough road game. Bayern is probably beaming. This result allows them to climb the ranks, and Bayern wont miss it.
Do we have to say that this result refers more to luck for the Dortmund camp? yes it is possible, it is very difficult to be able to break the consistency possessed by Leverkusen with their current performance position, statistics have shown that in that match Leverkusen was far superior to Dortmund, especially in terms of shots on target. This result reminds me of some previous matches when Leverkusen were able to hold Bayern Munich to a draw, I consider it natural because the performance of the two teams is currently almost equal, but on the other hand I cannot compare between Bayern Munich and Dortmund because in the past few seasons Bayern Munich has proven to be stronger than them by always being able to secure the trophy at the end of the season.
I honestly don't know what the problem was that Leverkusen were only able to hold a draw, and if they were late in equalizing then obviously it was a very surprising (bad) result for Leverkusen who played at home. In conclusion, in my opinion, it is not only luck that Dortmund has but they also have a very strong defense. On the other hand this is a pretty tough task for Xabi Alonso because after all their position is now getting closer to Bayern Munich in the standings, so there is no reason for Leverkusen not to perform optimally in the next match to secure three points.
