Bayer 04 Leverkusen 4-0 1. FC Union Berlin: Bundesliga Match Report, 5 September 2026

Bayer 04 Leverkusen 4-0 1. FC Union Berlin, two goals before the interval and two after it — an evenly distributed rout, if the half-time score of 2-0 is any guide, and it is the only guide the record provides.

The single number the preview leaned hardest on was Union's inability to score in this fixture away from home. Two goals in five recorded visits, both of them in the same match in January 2022, and blank in the four trips since. They were blank again. The whole case rested on a visiting attack that has not functioned in this fixture, and nothing in the record suggests it started functioning here.

The pre-match table, as usual after one round, was more misleading than helpful. Union arrived ninth on a point, from a 3-3 home draw with Eintracht Frankfurt; Leverkusen arrived thirteenth on none, beaten 3-2 away by newly promoted Elversberg after going two goals down before half-time. We ignored both, and the 34-match records behind them held up: Leverkusen sixth on 59 points with a 9-4-4 home ledger of 38 goals scored and 19 conceded, Union eleventh on 39 points with 5-2-10 on the road and eighteen away goals in seventeen matches. On the day it was the wrong table that looked silly, not the old one.

Four goals is above Leverkusen's home rate of 2.24 a game from last season, and one match does not raise that average into a trend.

Both clubs now have two matches played, which is not enough for a table to mean anything. Leverkusen have three points, Union one, and thirty-two rounds remain.

The more interesting note is about Union's away profile rather than the standings. Their 2025/26 road campaign was all-or-nothing — five wins, two draws, ten defeats — and the ten defeats were the price of an approach that produced the five wins. A four-goal loss is that distribution doing what it does, not a new problem.

For Leverkusen it settles less than the scoreline suggests. Nine home wins in seventeen last season with four home defeats is a good home record rather than a fortress, and a heavy win over a side that scored eighteen goals in seventeen away matches does not change the read. It does answer the opening-weekend defeat that had them thirteenth before kick-off. And Union, who had scored three against Frankfurt a week earlier, scored none here.

Our pre-match call was Bayer 04 Leverkusen Win at 1.52, rated medium confidence, and the medium rating was about the draw rather than the away win. Four of the ten recorded meetings between these clubs had finished level, two of them at this ground, and Leverkusen drew four of seventeen home matches last season. That was the scoreline that beat us, and it never appeared.

We wrote one line as a tripwire: if Union scored early here, the entire position was under review, because the case depended on a visiting attack that has not scored in this fixture since January 2022. They did not score at all. The bet asked one question and got the answer it was built on.

Verdict: won
