FSV Mainz 05, representing the Bundesliga in the UEFA Europa Conference League, carved out a significant moment in their club history and for German football on Thursday evening. Under Urs Fischer’s guidance, the Rheinhessen side triumphed over visitors SK Sigma Olomouc with a 2-0 aggregate score in the Round of 16. This decisive home win propelled Mainz into the quarterfinal stage of a European competition for the very first time.
Even before this crucial match, Mainz 05 had already established themselves as the most successful Bundesliga team in the five-year existence of the UECL, being the first to reach the Round of 16. Previous attempts by Eintracht Frankfurt (2023/24) and 1. FC Heidenheim (2024/25) in the playoff round had ended in defeat. Adding to Germany’s European success on the night, SC Freiburg also progressed to the Europa League quarterfinals in a parallel fixture.
Mainz Misses Opportunities in First Half
Due to a severe injury to attacker Silas, German striker Nelson Weiper, who has seen limited playtime, was given a rare starting opportunity. Both Weiper and Phillip Tietz created early scoring chances, but neither FSV forward truly tested the goalkeeper. Tietz’s shot in the 6th minute was delayed slightly, while Weiper’s header four minutes later was soft and straight at keeper Jan Kourtney. In the 18th minute, Paul Nebel, a player often under scrutiny, sent a promising chance high over the bar after some well-executed team play.
The Czech visitors, Olomouc, signaled their intent with a warning shot in the 20th minute, as striker Danijel Sturm narrowly missed the target following a superb counterattack. Despite this, Mainz still created the clearer opportunities. Phillipp Mwene struck a powerful shot just wide in the 36th minute. In first-half stoppage time, Weiper had another header from a Jae-Sung Lee cross but failed to direct it on goal, missing wide.
Stefan Posch Breaks the Deadlock
Weiper’s earlier heading woes were swiftly overshadowed immediately after the break. Crucial January signing Stefan Posch expertly connected with an excellent delivery from Nebel on the right wing in the 46th minute. The Austrian international’s perfectly placed glancing header gave Mainz a 1-0 lead. Buoyed by this vital goal, ‘the Nullfünfter’ pressed for a second. Both Tietz (56th minute) and Nebel (79th minute) went close, with Nebel’s late powerful strike rattling the crossbar.
Armindo Sieb Seals the Victory
The Czech side offered minimal resistance in their attempts to mount a comeback, and Mainz’s progression seemed almost certain. Any lingering hopes for Olomouc were effectively extinguished when Peter Barath received a second yellow card in the 76th minute, leading to his dismissal. Bayern Munich loanee Armindo Sieb, who replaced the less effective Weiper in the 74th minute, solidified the win in the 83rd minute, making it 2-0. Danny da Costa of Mainz provided a superb assist, simplifying the finish for the young attacker.
Mainz Player Ratings
Daniel Batz (5) – Dominik Kohr (5), Stefan Posch (7), Danny da Costa (7) – Phillipp Mwene (6), Jae-Sung Lee (6), Kaishu Sano (7), Paul Nebel (7), Silvan Widmer (7) – Phillip Tietz (7), Nelson Weiper (4)
Substitutes: Nikolas Veratschnig (6), Armindo Sieb (7), Kacper Potulski (-), Sota Kawasaki (-), Lennard Maloney (-)
Player of the Match: Phillip Tietz (7)
Selecting a Player of the Match was challenging, given that six players, including substitute Sieb, earned a rating of 7. The effort from Urs Fischer’s squad on this night was exceptionally high. Despite the Bundesliga club not finding the net in the first 45 minutes, their overall performance was undeniably dominant. There was a palpable feeling that the Pfälzer team would eventually break the deadlock in the second half.
Tietz received the Player of the Match award partly because he’s often an underrated contributor. The ex-Darmstadt and Augsburg player isn’t primarily known as a prolific goalscorer; he’s only scored once in 13 games since joining his new club in January. However, a center forward’s value extends beyond goals. Tietz has provided three assists in the Bundesliga and demonstrates an exceptional work ethic on the ball.
During the match, Tietz registered 43 touches, completed 31 passes, and successfully executed two long dribbles from deep positions. He played a crucial role in almost every promising FSV attack, aiding the team’s penetration into the final third. His engagement in 26 direct duels is remarkably high for a striker, underscoring the Braunschweig native’s tireless commitment throughout the game.
