Mainz
Mainz’s 2-2 draw away at Bayern Munich last weekend felt like a small breakthrough, but the bigger picture is still worrying for Mainz.
They are still ten Bundesliga games without a win, losing seven of those, which is the longest ongoing winless run in the league. Confidence has clearly taken a hit, and results simply haven’t followed performances for large parts of the season.
However, the atmosphere has improved greatly since Urs Fischer took over as head coach last week. Also, there has been a much brighter mood around the club in Europe.
Mainz have reached the round of 16 of a European competition for the first time in their history, and the 2-0 home win against Samsunspor last Thursday evening gave everyone a timely boost.
Their top player, Nadiem Amiri, summed it up well — a big step for the club, and hopefully a turning point domestically. Mainz will be desperate to carry that European positivity back into the Bundesliga before the winter break.
St.Pauli
St. Pauli finally got some breathing room last weekend with a 2-1 home win over Heidenheim, ending a brutal run of ten Bundesliga matches without a victory, nine of them defeats. That result alone lifted a lot of pressure, and it wasn’t an isolated performance either.
Including their DFB-Pokal win away at Borussia Mönchengladbach, and a hard-fought 1-1 draw in Köln, Alexander Blessin’s side are now unbeaten in three competitive matches.
However, this trip comes with a major setback. Defensive leader Eric Smith was sent off last weekend and is suspended, a big blow in what is a huge relegation battle game.
The Betting Verdict
Mainz looks like the safer side here. They already beat St.Pauli twice last season without conceding, winning 0-3 away and 2-0 at home, and that psychological edge matters in games like this.
With St. Pauli missing a key defender and Mainz showing signs of life, especially at home, the hosts feel better placed to finally end their long winless Bundesliga run.
