Mainz 05
The Germans had the upper hand in the first leg and even scored twice, but neither goal stood. As a result, the sides played out a goalless draw. Mainz 05 failed to score in the 2025/26 Conference League for only the second time, while Urs Fischer’s men recorded their fourth clean sheet. If another draw follows in the return match, extra time will be required. To avoid that, the team need to win, something the Germans have managed successfully in every home game in this season’s edition of the tournament.
- No more than two goals were scored in 6 of Mainz 05’s previous 7 Conference League matches.
- On home soil, the team have won five straight international fixtures.
- In their last nine home matches in European competition, the Germans have not conceded more than once.
Potential Mainz 05 Lineup (3-5-2)*
Daniel Batz – Dominik Kohr, Kacper Potulski, Stefan Posch – Paul Nebel, Kaishu Sano, Philipp Mwene, Danny da Costa, Vilyam Beving – Silas Mvumpa, Phillip Tietz.
Forwards Silas Mvumpa and Benedikt Hollerbach, as well as defenders Stefan Bell, Maxim Dal and Antoni Caci, and goalkeeper Robin Zentner, will miss the match through injury.
Sigma Olomouc
In the previous match, the Czechs achieved a small success, keeping their first clean sheet of this season’s tournament, although they also needed some luck. However, Tomas Janotka’s side also saw their scoring run of seven matches come to an end. To avoid extra time in the upcoming fixture, Sigma Olomouc need to win, but the team have triumphed in only one of their last five Conference League matches (two draws, two defeats).
- Both teams to score landed in 7 of the Czechs’ previous 8 Conference League matches.
- The team have not drawn in seven straight away games in European competition (three wins, four defeats).
- Sigma Olomouc have conceded in their last seven away matches in international competition.
Potential Sigma Olomouc Lineup (4-4-2)*
Jan Koutny – Jiri Spacil, Matej Hadas, Jiri Slama, Matus Maly – Ahmad Ghali, Jan Kliment, Peter Barat, Michal Beran – Antonin Rusek, Daniel Sturm.
The injury list includes forwards Yunusa Muritala and Artur Dolzhnikov, defender Jan Kral, and midfielders David Tkac and Filip Urica.

Mainz 05 vs Sigma Olomouc: Match Prediction
It is unlikely the Czechs will approach the match with the aim of winning in normal time. Aware of the opposition’s superior quality, Tomas Janotka’s men will first and foremost try not to concede. However, Sigma Olomouc have not managed that away from home in this season’s tournament. That is all the more telling given that even a representative from Gibraltar managed to find the back of the net twice against the club.
Mainz 05 have been flawless at home in the 2025/26 Conference League. The team have won all four home matches and conceded only two goals in the process. The hosts’ overall form also deserves credit, as Urs Fischer’s men have gone five competitive games without defeat, and during that run the club took points off two Bundesliga top-six sides.
The home team should secure a place in the quarter-finals in a low-scoring match.
Prediction: Mainz 05 to win + Under 3.5 goals
