You're right bayern munich need to be consistent in thier position and also try to win more matches so as to increase the point difference, because for the fact that they have 8points ahead of laverkusen does not guarantee them to be the champion this season. Because they are still in the middle of the season if I'm not mistaken, so anything can happen. As leverkusen is trying so hard to cover the point difference.
Although Bayer Leverkusen is still trying hard to reduce the points gap with Bayern Munich in the remaining matches which are quite a lot, I don't think that it will be easier for Leverkusen to do this season. Because from the current eight points gap, at least Munich has the opportunity to stay at the top of the Bundesliga standings if Munich loses again in one or two more matches in the Bundesliga. So Munich clearly will not be relaxed enough in facing such conditions for now because Munich will continue to try to add points in every match.
