Most teams have easier opponents this week, bundesliga is really a big surprise in a box so you never know what's going to happen but I believe this isn't going to be that much of a shocker result at all. Leverkusen is playing against Heidenheim, and there is no way that I would be convince to say that Leverkusen could lose this game, or even get a draw, it has to be a win and anything other than a win would really be a huge shock to the world.
Same logic applies to Dortmund as well, they are playing against Freiburg, while I know Freiburg is literally above Dortmund on the table, and doing good this season, if Dortmund wants to recover from the position they are in, they have to win this game, in fact this is the most important game they could win. Dortmund would become 19 points, and Freiburg will stay at 17 points and behind them without a trouble. So all in all betting on these two wins should be a fine one and could give a good result in the end.
