It's normal to drop point, and besides that, Gladbach is not a small team to underrate, they are not just in good form this season, therefore. dropping points against them is normal and I am still confident of Leverkusen in this season's Bundesliga title.
Bayern Munich might also drop points against Gladbach because when you go through the statistics of their last five matches, you will see a lot of possibilities for Bayern to drop points because Gladbach is always a strong opponent for Bayern Munich, and now that they are looking a way to accumulate some points in order to move up, I don't think they will take it easy with Munich either.
No doubt drooping points is normal but best thing which happen to Bayer Leverkusen is they are still undefeated after 19 rounds and their lead from Bayern Munich is still 2 points which could be vital for them in coming weeks Gladbach is surely one of the biggest clubs which having troubling time with their performance, but they have done good job against leaders and steal one point which is also good for them while they are currently near the danger zone with their coming game is against another giant club Bayern Munich even their performance and record against them is also good but still they need to be better and improved because now as we are heading for the last rounds things are looking more difficult for the teams which are not in good consistency because now any bad result can bring them in more trouble which can ended into relegation zone.
