It seems like that people are starting to feel doubt with union against dortmund. This is the most difficult match to predict since union has a bad history against dortmund but union was still the number first. Union must win to create a gap with dortmund but im sure dortmund will not give free points for union. Dortmund seem has more chance to win this game easily against union.
Union Berlin are on top of the bundesliga because they are playing well for now, they are not there by chance, but Dortmund is a bigger team than them in Germany, so whenever the two of them play against each other, people will always feel that Dortmund will win the game. I want Dortmund to win, if Union Berlin win Dortmund will fall below and will not be close to the top of the table, i do not have any problem with Union Berlin being in first place, but i don't think they can win the bundesliga, and if they are the only competitors to bayern, they will surely lose out. It is Dortmund that has that small chance to dethrone bayern, so i want them to be very close to the top of the table, and a win will do that for them.
