Agree with what you said because indeed 9 matches have been run this season they are the club that has conceded the fewest goals because only 6 goals have been in Ronnow's goal.
But indeed this can still change because even in this case Union is still very good but I am a little doubtful whether they can still be consistent or not in the upcoming matches.
A little doubtful aswell if Union Berlin can manage to still stay at the top until the end of the season, right now I am seeing Freiburg that is the 2nd and near Union Berlin right now, and Bayern Munich that is showing progress with their formation and Sadio Mane is getting a hang on the previous Bayern Munich play, Dortmund Bayern's rival is seemingly getting back to it again, and getting really good in making an equal to Bayern and their recent game was a Draw And Werder that comes from the promotion on the 2nd division I guess they are doing pretty much great right now and getting into it this time,
Union Berlin will obviously have to win this match against Dortmund. Unless they do so, they are at risk of losing the first place on the table.
Now my prediction is that Bayern Munich is likely to win against Freiburg and Union Berlin is almost certain to lose against Dortmund.
The result will put Bayern Munich in second place and Dortmund in third. But Union Berlin is still expected to be at the top.
The difference is going to be that they will face a lot more competition and pressure from both Bayern Munich and Dortmund.
But if Freiburg wins the match against Bayern Munich, they will take over the lead(1st place) if Union Berlin loses
.
These are going to be the most significant two matches for all four teams in my opinion.
After that loss to Frankturf, I now doubt if Union Berlin will be a dominant team against Dortmund or if they are lucky yet again in winning against Dortmund that will be great because Dortmund is now having a great time with their matches and now they are improving even without Erling Halland, or Sebastien Haller,
Yeah now that Bayern Munich's formation are all switched and good Sadio Mane is performing well, and every player had their chance now to gazing the goal, for me their are the favorite to win and the odds are back again to Bayern Munich,
