Saturday afternoon at the Stadion An der Alten Försterei sees Union Berlin host Mainz 05 in a Bundesliga clash that has historically been one-sided.
Union Berlin have dominated this fixture in recent years and find themselves comfortably mid-table, while Mainz sit bottom and desperately seek to reverse their fortunes. Kick-off is scheduled for 10 January 2026, with both sides under pressure for different reasons.
Union’s physical style and home advantage meet a Mainz side with only one league win all season, making this a pivotal encounter as the relegation battle intensifies.

Season Form & Standings
Union Berlin have established themselves in mid-table with a balanced record, while Mainz 05 are entrenched at the foot of the table with just a single victory and the league’s worst defensive numbers.
| Team | Pos | P | W | D | L | GF | GA | GD | Pts |
|---|---|---|---|---|---|---|---|---|---|
| Union Berlin | 8 | 15 | 6 | 3 | 6 | 20 | 23 | -3 | 21 |
| Mainz 05 | 18 | 15 | 1 | 5 | 9 | 13 | 26 | -13 | 8 |
Potential Match-Winners
Neither side boasts players among the league’s top scorers or assist providers, but Union Berlin’s strength lies in its physical and aerial game, with 320 successful aerial duels this season. Oliver Burke and Andrej Ilić could be key up front, while Josip Juranović (135 tackles won) anchors the defence. For Mainz, William Bøving Wick and Armindo Sieb provide the main threat in attack, but the side has struggled to convert chances—just 13 goals from 15 matches, despite creating 19 big chances.

Head-to-Head: Last 5 Meetings
Union Berlin have dominated this fixture, winning seven of their last 12 meetings with Mainz 05, who have managed just one victory in that span. Draws are not uncommon, but the recent trend clearly favours the home side.
| Date | Score | Competition |
|---|---|---|
| 19/01/25 | Union Berlin 2-1 Mainz 05 | Bundesliga |
| 24/08/24 | Mainz 05 1-1 Union Berlin | Bundesliga |
| 07/02/24 | Mainz 05 1-1 Union Berlin | Bundesliga |
| 20/08/23 | Union Berlin 4-1 Mainz 05 | Bundesliga |
| 04/02/23 | Union Berlin 2-1 Mainz 05 | Bundesliga |
Conclusion
Union Berlin’s powerful home record against Mainz and their mid-table stability make them clear favourites, but Mainz’s desperation could make this a cagey affair. Will Union’s physical edge and clinical finishing see them to another win, or can Mainz upset the odds at last? Backing the home side at 11/10 @ Betfair (47.6%) looks the standout value.
