Cologne – Union Berlin Tip Bundesliga, Matchday 15 on Saturday, 20.12.2025 at 15:30 CET
It is difficult to say where both clubs will end up in the long term. At the moment, they are commuting around in the no man’s land of the Bundesliga, although the promoted team can be much more satisfied with its current table situation.
But in my Köln Union Berlin tip, I’m only concerned with successful football bets on the last Bundesliga matchday of 2025. Who wins? Where can I find the best odds boost?
In my opinion, you would be well advised to make a simple over-2.5 goal bet. Because the German top flight of football, with an average of 3.22 booths per point game, remains fertile ground for this type of betting, which is popular among sports betting fans.
And did you know that the Rhein-Energie Stadium has scored an incredible 4.00 goals per game on average since the start of the season and that this type of bet would have been successful in 10 of its last 12 home games?
I like to predict goals at the Rhein-Energie Stadium, but I deliberately hold back when it comes to a home win – and for good reason.
The direct comparison speaks clearly against the Effzeh: The promoted team has won only one of the last ten Bundesliga duels with Union Berlin (2 draws, 7 defeats), but of all things the last meeting at home in the 2023/24 season (3-2).
Against no other club does Cologne have such a high defeat rate in the top flight as against Union (70%), which makes a home win bet much riskier than the goal bet I have in mind.
Cologne – Union Berlin Prediction & Betting
As the main tip suggests, my Cologne Union Berlin prediction focuses on goal bets of all kinds.
“Both teams score” at odds around 1.75 is almost a must and ideal as a bonus to my tip from the headline, especially since each of the seven home games of the Domstadt team met this condition.
“2nd half: Cologne over 0.5 goals” is also worth considering at 1.72, maybe you should even consider a brace of the goats after the change of ends.
Cologne has scored the most goals in the league within the final quarter of an hour (11), whereas Union Berlin, of all teams, has conceded the second most Bundesliga goals in this time window (8).
What you need to know about Cologne vs. Union Berlin betting

- Union Berlin matches have so far recorded the fifth most cards in the league. The direct style of play of Steffen Baumgart (Cologne coach) provokes fouls and cards.
- The Bundesliga has the highest average of all top 5 leagues in Europe with 3.22 goals per game. For Köln, 71% of league matches have ended with goals for both teams (joint high).
- Cologne’s Marius Bülter and Ragnar Ache are the favorites on the goal scorer market, although they have only scored four goals together this season. Cologne’s Said El Mala, who has already scored six league goals, is also considered the favourite.
Cologne – Union Berlin: AI Tip & Odds Analysis
Our Köln Union Berlin AI prediction knows game-theoretical answers to questions that I don’t quite dare to answer due to the balance of both teams.
In any case, with regard to the outcome of the game, I am convinced by the suggestion to consider a draw bet at odds of around 3.40. The AI is right on this point – it’s the best 1X2 bet in terms of reward-to-risk ratio.
The selection “Andrej Ilic to score” is recommended by our data model at odds around 4.05 as a goal bet, but I urge caution.
Because the Union Berlin player is indeed involved in many goals of the Irons, but mostly “only” in the function of the provider of assists. This season, only Bayern pro Olise (8) has collected more assists than him (6) in the league.
The best odds for Cologne vs. Union Berlin
If we look at the Köln Union Berlin odds, it is immediately noticeable that the betting markets act much more cautiously here than in many other games. A clear favourite is not declared – instead, a lot of respect for both approaches is reflected in the figures.
A home win for the promoted team is scheduled at 2.35. The bookmakers have a lot of confidence in Cologne in front of their own crowd, see the Effzeh as having a slight advantage, but far from dominant. Factors such as intensity, home crowd and physical play are visibly reflected here.
The draw is traded at 3.40. This rate suits two teams that act in a structured way, give little away and like to control games through control instead of risk. For the markets, a shared point win is an absolutely realistic scenario.
An away win by Union Berlin is 3.20. The Irons are thus only minimally ranked behind Cologne. Defensive stability, transition moments and maturity ensure that Union is taken seriously despite the away game.
The Köln Union Berlin odds thus convey a balanced market picture: Cologne slightly preferred, Union always dangerous – a game in which little things and phases of the game are likely to be decisive.
Cologne vs Union Berlin Match Analysis:
Cologne and Union Berlin go into this duel almost on an equal footing. Only two points and two places in the table separate the teams, which indicates a close game.
Both teams often act from a deeper basic order – be it out of conviction or due to a lack of dominance. This is also shown by the field tilt, where Union is fourth last in the league, directly behind Cologne.
Longer phases of possession are not particularly good for either team, which is why a disjointed game with many transition moments is likely. Technical control will remain a scarce commodity, but intensity and duels are likely to be the focus.
Union games are among the richest in the league – currently the fifth-highest value. Baumgart’s team does not shy away from a duel, plays directly forward and often forces opponents to commit tactical fouls.
In view of the expected counterattacks, there are likely to be more yellows, especially in midfield. Cologne itself is dangerous at home despite little control of the game, but pays a price defensively: home games average four goals.
This speaks for open phases, many penalty area scenes and mistakes on both sides. A controlled chess game is not to be expected – rather an intense, wild Bundesliga duel with chances on both sides.
Cologne Form Check
Cologne has been waiting for another three points since the 4-1 home win against HSV in November and has only taken two points from the last five games.
With an average of 0.40 points per game, they are one of the weakest Bundesliga duo in this period – together with Mainz. For the promoted team, the danger of slipping into a relegation battle early on is growing.
Most recently, they suffered a deserved 2-0 defeat against Leverkusen in the small Rhine derby, in which Cologne hardly took place offensively and produced only 0.15 expected goals.
Nevertheless, the basic orientation under Lukas Kwasniok is by no means defensive. Cologne has the eighth-best offense in the league with 1.57 goals per game, and is in the top third in terms of shots on goal (4.64) and penalty area contacts (22.07).
The main problem lies in the balance: Cologne often takes too many risks, conceding an average of 1.61 xG per game and allowing many shots from their own penalty area.
The fact that goalkeeper Marvin Schwäbe is one of the busiest keepers with 3.21 saves per 90 minutes underlines this weakness.
Cologne remain dangerous at home: Four goals against Freiburg and HSV and three against Frankfurt show that the offense continues to carry in their own stadium.
Union Berlin Form Check
Union Berlin ended a three-game drought with a 3-1 win against Leipzig on Friday and are now in eighth place with 18 points. It is their best start to the season since 2022/23, when they were even second after 14 matchdays.
Strikingly, Union has already played against all teams in the current top 9 and has collected a strong 11 points and 13 goals. In the DFB Cup against Bayern, they also showed offensive qualities with two goals, but lost narrowly 3-2.
Despite these results, the quality of opportunities remains an issue. With only 1.18 expected goals per game, Union is one of the four weakest teams in the league in this category.
The record against supposedly weaker opponents is also problematic: Union remained winless in the last three Bundesliga games against promoted teams.
The Berliners have only scored six goals away from home so far, an average of one per game, similar to last season. What is new, however, is that they have not yet drawn away from home.
Union deliberately refrains from high pressing (PPDA 17.2) and instead relies on structure. The creativity of Andrej Ilic, who is one of the top in the league with six assists, remains decisive.
