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.
I think Bayer Leverkusen will only have the opportunity to reduce the gap if they win matches and Bayern Munich end up losing fe matches but from what is happening now Bayern Munich looks more better in performance they are winning matches and trying to avoid defeats that will see them drop points for Leverkusen to get closer to them in my opinion I think this season Bayer Leverkusen has to keep trying despite their inconsistent performance thus season all they need is to maintain their position while they hope for Bayern Munich to make one mistake so hey can seize the opportunity to get closer. Vincent Kompany understands the current situation of things in the league that's why his is not accepting any defeat so far id they are able to hold on to the point they may end up becoming champions while Bayer Leverkusen will try next season.
