Leverkusen needs to be a little more patient because they still have a long way to go, even though they can't take advantage of Bayern Munich defeat, at least they can take advantage of Bayern Munich busy schedule in the UCL competition. Because sharing points with Stuttgart is a worthy result for both of them in optimal conditions. After Bayern Munich faces Man United, they will also face Stuttgart so this could be a good opportunity to prevent Bayern Munich from chasing Leverkusen points. But because they also have to face Frankfurt, it is certain that the obstacles before their eyes will not be easy.
2 draws in two matches meant they failed to take advantage of the opportunity to widen the points difference between the poor results achieved by Bayern Munich. But the two matches that leverkusen have played were quite tough for them and I think a draw is a fairly fair result when measured by the strength of their opponents. VFB had put on strong pressure in yesterday match where VFB was able to make 22 shots and 12 were on target which enabled them to score more than 1 goal l. but that didn't happen because Hradecky performed well in guarding the goal and blocked several quite good shots.
Leverkusen is 4 points ahead of Bayern Munich, they must be able to work well so they don't lose any more points. Xabi Alonso was very clever in turning things around if we look at the previous two matches because Leverkusen had fallen behind but was able to equalize.
