Borussia Dortmund on the other hand is also a good team but they are not much consistent as Leipzig on this league so their chances of wining the match becomes very small, however looking at the bright side of it all Leipzig needs is just to win or they draw because their point is still higher than Borussia Dortmund, so they stand on more better chance on this match including their home advantage.
I would say for the last 3 weeks Dortmund was more coming consistent as before and we have seen that in the Champions League games too.
Playing a draw against Leverkusen was also good and shows that Dortmund can be playing very good against other good teams.
About that i say that there chances are not small to win the coming game , it all depends on the daily performance on that day.
It will be hard as Leipzig playing at home but its possible for Dortmund.
