Mainz vs St Pauli Prediction 21 December 2025
🔊 Will Mainz secure their first home victory in the 15th round of the Bundesliga? In the final match of 2025 at the MEWA Arena, Urs Fischer's side aim to head into the winter break on a positive note. Sitting at the bottom of the table in 18th place, Mainz will host fellow relegation battlers St. Pauli, who finally ended their winless streak last weekend after 11 matches. Notably, in their Bundesliga head-to-head history, the "Pirates" have never taken points from the "05ers"-four matches, four losses. Could this be the perfect opponent for Mainz to break their extended winless home streak, which stretches to 12 matches since the end of last season? It's also symbolic that their last league victory came against St. Pauli on February 22, 2025, with a 2-0 result.
Head-to-Head
📊 Last season, Mainz defeated the Pirates twice: 2-0 at home and 3-0 away. Additionally, Mainz also triumphed over the Hamburg club in both of their only previous Bundesliga encounters during the 2010/11 season. As a result, Mainz remains the only team with a perfect winning record against St. Pauli in the history of the top division.
Head-to-head statistics Mainz - St Pauli

Mainz Team Overview
🔴 In their Bundesliga debut under new head coach Urs Fischer, Mainz came close to handing the season leaders Bayern Munich their first defeat in the league (2-2). Kacper Potulski equalized before halftime, and Lee Jae-sung put the "05ers" ahead in the 67th minute. However, a late penalty awarded to the hosts allowed Bayern to salvage a point. Special mention goes to Mainz's reserve goalkeeper Daniel Batz, stepping in for the injured Robin Zentner, who made eight crucial saves at the Allianz Arena. Despite a commendable draw with Bayern, Mainz are winless in their last ten Bundesliga matches (seven losses), marking the longest current winless streak in the league.
⚪ The "05ers" will remain at the bottom of the table regardless of the outcomes in matchday 15, but a victory could narrow their gap to St. Pauli to just one point. Mainz are the only Bundesliga team yet to secure a home win this season. They also share the lowest tally of goals scored (13) with Heidenheim and St. Pauli.
🏆 In European competitions, however, Mainz have fared significantly better at home. On Thursday at the MEWA Arena, they played their final group stage match of the Conference League against Turkey's Samsunspor (2-0). A win was crucial for direct qualification to the Round of 16, and the "05ers" delivered: Silvan Widmer and Nadim Amiri, who converted a penalty, found the net. This match marked Urs Fischer's third in charge (he debuted in the Conference League's fifth round against Poland's Lech Poznań - 1-1), and under the Swiss coach, Mainz have yet to suffer a defeat.

St. Pauli Team Overview
🟤 A crucial 2-1 victory over Heidenheim has bolstered St. Pauli's confidence in their fight to stay in the league. Martijn Kaars opened the scoring in the 35th minute, but just before halftime, the "Pirates" were reduced to ten men as Eric Smith saw red for a last-man foul. In the second half, Alexander Blessin's side mostly defended and looked for counter-attacking opportunities. They capitalized on one such chance, with Kaars netting again to secure his brace. Midway through the second half, the opposition managed to pull one back, but St. Pauli held firm to prevent any further goals.
⚪ The four points picked up in the last two rounds have lifted the Hamburg club into the playoff zone, cutting the gap to safety to just two points. However, they still face the risk of spending the winter break in the automatic relegation zone if results elsewhere don't go their way.
🏴☠️ The win over Heidenheim also snapped St. Pauli's ten-game Bundesliga winless streak (nine losses and one draw). Including their success in the German Cup against Borussia Mönchengladbach (2-1) and a draw with Cologne (1-1), Blessin's team is now unbeaten in three consecutive official matches.

Latest news
Mainz
🎙 Midfielder Paul Nebel after the Conference League victory: "It was a strong performance both offensively and defensively. We had a clear plan that we stuck to until the end. In recent weeks, it's been evident that we're on the right track, and today we finally managed to secure a win. Of course, we want to carry this momentum into Sunday's match."
❌ Anthony Caci (hamstring), Maxim Dahl (knee), Maxim Leitsch (thigh), Philipp Mwene (groin), and Robin Zentner (groin) continue their recovery. The participation of Sota Kawasaki (thigh) and Silvan Widmer (calf) remains doubtful.
St. Pauli
🎙 Karol Mets, a key figure in St. Pauli's defense, stated: "I believe we've identified the reasons why things weren't working out before. We've drawn the right conclusions, and it's starting to pay off. We need to keep going in the same direction. This match is even more important than the game against Heidenheim. Both teams understand its significance. We're up against a physically strong and aggressive opponent. They're a good team that, in my opinion, is positioned too low in the standings."
❌ Eric Smith will miss the match due to a suspension from the last round. David Nemeth (groin) and Simon Zander (ankle) will also be unavailable. The participation of Ricky-Jade Jones and Andreas Untondji remains uncertain.
🟨 Referee and Yellow Cards
The main referee for the match is Matthias Jollenbeck. In his last ten matches, he has averaged 3.5 yellow cards per game. Mainz have an average of 2.4 yellow cards per match, while St. Pauli average 1.8. Given this, a bet on Mainz's individual total under 2.5 yellow cards seems reasonable, as this outcome has occurred in the last six matches for the "Nullfünfer".
⚽ Goal Prediction
Considering Mainz's defensive struggles-they have conceded in every match of the current championship-we anticipate a goal from St. Pauli at the "MEWA Arena". Blessin's side have scored in four consecutive games, which strengthens this prediction.
🚩 Corner Prediction
Mainz average 4.8 corners per game, while St. Pauli average 5.1. Nonetheless, we opt for St. Pauli's individual total under 4.5 corners, which has been successful in 10 of their last 11 matches, including seven consecutive away games for the "Pirates".
Editor's Prediction
We are in for a thrilling clash between two underdogs, where a high-scoring game is expected. The main pick is both teams to score (yes): Mainz have yet to keep a clean sheet in the current league campaign, and this outcome has occurred in St. Pauli's last four matches consecutively.
Moreover, in recent weeks, it’s evident that Urs Fischer has made quick adjustments to the "Nullfünfer" gameplay. We might witness Mainz's gradual resurgence, similar to what Eugen Polanski managed at Gladbach earlier. It's plausible that the hosts will break their unfortunate home streak in the Bundesliga and secure a much-needed victory. The predicted score is a 2-1 win for Mainz.
