Union Berlin's Defensive Crisis Hands Dortmund a Golden Opportunity

Union Berlin vs Borussia Dortmund. Saturday 17 October 2026. Thirteen-thirty UK time. On paper it looks like a football match. In practice, it looks like a firing squad.

I will tell you exactly what I see here. Union Berlin are a side in trouble. Their recent form across five Bundesliga matches reads two wins, one draw and two losses. The numbers sound manageable until you look at the goals against column. Eleven conceded in those five games. One clean sheet in five. That is not a defence with problems. That is a defence that has stopped functioning.

Union Berlin: A Club Running on Empty

The thing is, Union Berlin's issues go beyond a bad run. Look at the last ten Bundesliga matches and the picture gets uglier. Two wins. Three draws. Five defeats. Seventeen goals scored. Twenty-two conceded. A clean sheet rate of ten per cent. These are not the numbers of a team going through a rough patch. These are the numbers of a team with a serious attitude problem towards defending.

Their most recent Bundesliga result tells you everything. Union Berlin lost to Schalke 04, going down 1-3. Before that, Bayer Leverkusen put four past them without reply. They drew 3-3 with Eintracht Frankfurt before that. Goal after goal going in at their end and not enough accountability in the camp about why.

And now add the injury and suspension situation. Union Berlin head into this fixture with six players unavailable. Two are long-term injury absences with no expected return dates. Two are suspended. Another is out with a minor injury. One has a suspension running until late October. That is not a thin squad. That is a threadbare one. You cannot cover that many absentees without it showing on the pitch. It will show on Saturday.

Borussia Dortmund: Five Wins and No Sign of Stopping

Borussia Dortmund arrive in Berlin having won their last five Bundesliga matches without dropping a point. Thirteen goals scored. Four conceded. Three clean sheets in five. That is a side with confidence, with momentum, and with the basics working properly.

Their most recent result was a 3-0 win over Paderborn. Before that they beat 1899 Hoffenheim 3-2 and Hamburger SV 2-0. They are scoring goals and they are keeping clean sheets at a rate of sixty per cent over that five-match window. That is exactly what a good side looks like when it is clicking.

Stretch the window to ten matches and Dortmund have seven wins, zero draws and three losses. Fifty per cent clean sheet rate. Twenty goals scored against only eight conceded. The losses came against Borussia Monchengladbach, 1899 Hoffenheim and Bayer Leverkusen. None of those results suggest a team that folds. They suggest a team that occasionally comes up against quality opposition and gets beaten. That is not a character flaw. That is just football.

Head to Head: The History Is Brutal for Union

Listen, the head-to-head record between these two clubs in the available data is not something Union Berlin will want to think about too hard. Two meetings. Dortmund have won both. Six goals scored by Dortmund. Zero conceded. Both results were clean sheets for Dortmund. Both games went over two and a half goals.

The last meeting between the sides ended 0-3. Not 1-3. Not 2-3. A shutout. Union Berlin scored nothing. That is the standard Dortmund have set in this fixture and nothing in Union's current form suggests they are equipped to change that narrative this weekend.

The Numbers Do Not Lie

Union Berlin have conceded in eight of their last ten Bundesliga matches. Their both-teams-to-score rate sits at eighty per cent across that ten-match sample. Their clean sheet rate is ten per cent. They are conceding almost everywhere, against almost everyone.

Dortmund, in contrast, have kept clean sheets in five of their last ten Bundesliga outings. In the last five specifically, they have conceded just four goals across five matches. The gap in defensive solidity between these two clubs right now is not small. It is enormous.

The thing is, Dortmund do not need to do anything special here. They just need to compete at their normal level. Against a Union Berlin side missing six players and leaking goals at an alarming rate, that should be more than enough.

What Has to Happen for Union Berlin to Get Anything

Union Berlin need a defensive performance they have not produced consistently in recent weeks. They need the players available to them to show a desire to work harder than they have been. They need organisation, concentration for ninety minutes, and someone in that dressing room to demand standards.

Two wins against FC Augsburg and FSV Mainz earlier in their five-match sample show Union Berlin can score and can win. Those results are there. But the losses to Leverkusen and Schalke show what happens when the defence switches off and the side concedes the first goal. They fall apart quickly. Against a Dortmund side on this kind of run, falling apart quickly is simply not an option.

The Verdict

Borussia Dortmund win this football match. That is my call. Not because Union Berlin are a bad club. Not because there is anything personal about it. Because the form is clear, the head-to-head record is clear, the injury situation is clear, and the defensive numbers are unacceptable for a side trying to stop a team as sharp as Dortmund are right now.

Dortmund have the basics right. They are competing. They are keeping clean sheets. They are travelling to Berlin with five wins behind them and zero reason to drop their standards. Union Berlin are patched up, leaking goals, and coming into this match off the back of losing to Schalke.

Back Dortmund. Back them with conviction. End of.
