1. FC Köln put five past Union Berlin to reach the DFB-Pokal round of 16

Two clubs stuck in the bottom half of the Bundesliga met at the RheinEnergieStadion with a round-of-16 place on the line, and only one of them turned up. 1. FC Köln beat 1. FC Union Berlin 5-0, a scoreline that flattens any idea this was a close cup tie between league rivals.

Said El Mala did the early damage, scoring either side of the hour mark, either side of Linton Maina's goal in between. Ísak Jóhannesson and Sebastian Sebulonsen added two more in the closing stages, both introduced from the bench, to turn a comfortable lead into a rout.

Goal by goal

• 32' — Said El Mala (1. FC Köln)
• 51' — Linton Maina (1. FC Köln)
• 60' — Said El Mala (1. FC Köln)
• 78' — Ísak Jóhannesson (1. FC Köln)
• 88' — Sebastian Sebulonsen (1. FC Köln)

El Mala's second goal, on the hour, was the one that killed off any thought of a comeback — Union Berlin had barely threatened before it and stopped altogether after it. The last two goals, from a pair of substitutes, were more about the gulf in sharpness than any late Köln push: by then Union were chasing shadows in a game that had been decided for half an hour.

A night that got worse as it went

Union Berlin picked up two yellow cards, to Leopold Querfeld and Marin Ljubicic, both after the scoreline was already out of reach — a sign of a side losing patience rather than a tactical foul count. Köln's only caution went to Sebulonsen, four minutes after he had scored, and neither side saw red.

Köln used their bench early and often, making five changes across the second half, including both players who went on to score. Union made the same number of substitutions, among them Emmanuel Latte Lath and Marin Ljubicic, but none of their five changes altered the picture.

Two Bundesliga strugglers, two different directions

The result reads differently depending on which end of the table you check. Köln arrived into the tie 12th in the Bundesliga on 8 points from seven games, with a run of a win, a draw, a loss, a win, a loss and a draw in their last six — mid-table form, nothing more. Union Berlin came in 17th on 6 points, with 18 goals conceded in seven games, the clearest sign of a defence that has been porous all season and did nothing here to suggest otherwise.

That gap showed on the pitch. Köln's front three of El Mala, Maina and Marius Bulter started the game and caused problems throughout, while Union's back line never settled into a shape that could contain them — a repeat of the pattern that has already cost Union 18 goals in seven league games this season.

What's next

1. FC Köln advance to the DFB-Pokal round of 16, with that draw still to be made. Union Berlin's cup run ends here, and both sides turn straight back to the Bundesliga, where Köln sit 12th and Union 17th — with the two clubs due to meet again at the Alte Försterei within days of this tie.
