Union Berlin is definitely going to get relegated. Because they will play the next match against Freiburg. It is definite that Union Berlin is not going to win that match. So, unless they are able to win that match, and at the same time the teams that are above them lose, Union Berlin is definitely going to get relegated.
well, I think I should be a little more specific. Union Berlin is definitely going to play in the relegation playoffs. So if they do finish on that position and play well in the relegation playoff match they will have a chance to stay in the Bundesliga, if they win that match. but if they are unable to win the relegation playoff match, considering they finish in the 16th position in the Bundesliga this season, they will definitely face relegation and not play in the Bundesliga the next season. looking at the current performance that they are showing, I think it is going to be foolish to expect a lot from them at this moment.
There is a big possibility that Union Berlin will lose in the match against Freiburg, but it does not rule out the possibility, if Union Berlin is able to secure its position. with the condition that Mainz, the team that is above Union Berlin's ranking, suffers defeat. but it seems like Union Berlin is really having difficulty getting up from their downturn, they experienced a series of bad matches this season and were only able to win 8 of their 33 matches.
So we agree, the probability of being relegated is quite high for Union Berlin. It's a shame if that's the case, even though in the previous season Union Berlin was quite troublesome for the top teams in the Bundesliga. well, if in next week's match Union Berlin is unable to win the match against Freiburg. That means, it is very likely that Union Berlin will remain in 16th place.
As for Koln, it seems difficult for them to win the match against Heidenheim with a big score. At a minimum, Koln must score 5-6 goals to shift Union Berlin's position.
Let's just assume that Union Berlin can still fight in the playoffs, as you said. However, with current performance conditions, the chances of dropping from caste seem to be more in favor of Union Berlin. I mean, there is a big possibility that Union Berlin will not compete next summer in the Bundesliga. But we'll see how things develop, because the Union Berlin vs Freiburg match hasn't been held yet.
