Bayer Leverkusen 4-0 Union Berlin: A Statement Win That Felt Like a Reset
Saturday afternoon at the BayArena had that familiar late-summer feel — warm enough that the floodlights weren’t yet necessary, the stands mostly full at 29,629, and a crowd still carrying a bit of the hangover from the previous week’s embarrassment. Bayer Leverkusen, under new head coach Carles Martínez, had opened the Bundesliga season with a 3-2 loss at newly promoted Elversberg. It was the kind of result that makes you question everything for a few days. Union Berlin, meanwhile, arrived looking solid enough after a 3-3 draw with Eintracht Frankfurt, still searching for that first-ever league win at this ground since their promotion in 2019.
By the final whistle it was 4-0, and it felt like more than three points. It felt like the first proper chapter of the Martínez era.
The Preview: Pressure, Patience and a New Left Side
Going into the game, the narrative was simple. Leverkusen needed a response. Martínez, the 42-year-old Spaniard who arrived from Toulouse in the summer after a solid three-year stint in Ligue 1 and earlier years at Barcelona’s La Masia, had spoken about energy, passion and winning the individual battles. He inherited a squad still adjusting after the Xabi Alonso years and the subsequent transition under Kasper Hjulmand. Key summer arrivals included Spanish left-back Miguel Gutiérrez from Napoli (to replace the departed Álex Grimaldo) and the continued development of young attackers like Ibrahim Maza, the Algerian international who came from Hertha a year earlier.
Union under Mauro Lustrinelli were expected to be compact, physical and dangerous on the break. They had never beaten Leverkusen away in the Bundesliga and this was their eighth attempt. The smart money was on a home win, but after Elversberg, nobody in Leverkusen was taking anything for granted.
Martínez went with a 4-2-3-1. Mark Flekken in goal. Jarell Quansah, Edmond Tapsoba and Facundo Medina across the back with Gutiérrez at left-back. Ezequiel “Equi” Fernández and Aleix García anchoring midfield. Ibrahim Maza, Malik Tillman and Afonso Moreira supporting Patrik Schick up top. Union lined up in a more rigid 4-4-2, looking to stay organised and frustrate.
What nobody expected was that the game would effectively be decided before most people had finished their first beer.
The Match: Early Fireworks and Total Control
Forty-four seconds. That’s how long it took.
A move down the right, the ball worked wide to Gutiérrez, who had already pushed high. He kept it alive on the byline and cut it back for Fernández, who finished from close range for his first Leverkusen goal. The BayArena erupted. Union looked stunned. The earliest goal they had conceded in their Bundesliga history.
From that moment the hosts controlled the tempo. Possession hovered around 64 percent. Leverkusen moved the ball with patience and purpose. Gutiérrez was a constant threat down the left, overlapping and delivering. Maza drifted between the lines, finding pockets of space. Schick occupied the centre-backs.
Just before the half-hour mark Schick headed against the crossbar. Seconds later the second goal arrived. Again it was Gutiérrez, this time with a pinpoint cross from the left. Medina rose and headed home — another first Bundesliga goal, another Argentine on the scoresheet. 2-0 at half-time, and it could easily have been more.
Union had offered almost nothing. Five shots in the entire match, zero on target. Their expected goals figure sat at a miserable 0.4 while Leverkusen’s climbed toward 2.85. Mark Flekken barely had a save to make.
The second half started the same way the first had. Three minutes in, Quansah drove forward on the right and slid a low ball across the face of goal. Schick, left-footed, finished calmly for 3-0. The Czech striker now had a goal and, later, an assist. He looked sharp, confident, the focal point Martínez clearly wants him to be.
Union tried a triple change around the hour mark. Lustrinelli threw on fresh legs, including Emmanuel Latte Lath. It made little difference. In the 66th minute came the best goal of the afternoon. Maza exchanged a neat one-two with Schick on the edge of the box, danced past two defenders with that low centre of gravity and quick feet that have already earned him comparisons to a young street footballer, and curled a right-footed shot into the far corner. 4-0. The former Hertha player, still only 20, was the standout performer on the pitch.
Leverkusen eased off after that. Substitutions came — Loïc Badé, Robert Andrich, Lucas Vázquez and others. The clean sheet was never seriously threatened. Yellow cards for Gutiérrez (time-wasting) and Maza (late argument) were the only real footnotes. Referee Robin Braun had a quiet afternoon.
Top Highlights
- The 44-second opener — Fernández’s clinical finish from Gutiérrez’s cut-back set the tone for the entire match. Union never recovered from the early shock.
- Gutiérrez’s two assists — The new left-back looked every bit the replacement for Grimaldo. Two assists, constant energy, and a performance that will have Leverkusen fans dreaming of another Spanish full-back dominating that flank.
- Medina’s headed second — A centre-back scoring with his first real chance of the season, from another excellent Gutiérrez delivery. Symbolic of the defensive solidity and attacking contribution Martínez wants from his back line.
- Schick’s clinical third — Three minutes into the second half, a simple but perfect finish that killed any lingering hope Union had of a comeback.
- Maza’s solo fourth — The pick of the goals. Give-and-go, two defenders left on the floor, and a precise finish. The kind of moment that makes you sit up and take notice of a young player’s ceiling.
Analysis: What It Told Us
This was not just a win. It was a statement of intent from a team that needed one. After the chaotic opening loss at Elversberg — where they had conceded three goals before finding any rhythm — Martínez’s side looked organised, aggressive without the ball and fluent with it. The high press forced Union into errors. The midfield pair of Fernández and García controlled the centre. The wide areas, especially Gutiérrez’s side, created constant overloads.
Gutiérrez deserves special mention. Signed in early August from Napoli for a reported €25-30 million, he already looks at home. His delivery for both first-half goals was excellent, and he covered the ground of a modern full-back without neglecting his defensive duties. Pairing him with Maza on that left side gives Leverkusen a dynamic that can hurt teams all season.
Maza himself continues to look like one of the smartest signings of the previous window. Technical, brave on the ball, and increasingly decisive. His goal was pure quality, but his overall influence — the flicks, the presses, the link-up play — was just as important. At 20 he already carries himself like a player who belongs at this level.
Schick’s contribution was classic Schick. He doesn’t need 15 touches to be effective. Positioned well, clinical when the chance came, and generous with the assist for Maza. If he stays fit, Leverkusen have a reliable focal point.
For Union the afternoon was a reminder of the gap that still exists against the better sides when they are on form. They were passive, created almost nothing, and looked short of ideas once they fell behind. Lustrinelli’s side will have better days — they are organised and hard to break down on their own pitch — but away from home against top sides they still lack a cutting edge.
Martínez’s first Bundesliga win will quiet some of the early noise. The Spaniard has spoken about building a team that plays with intensity and clear principles. On this evidence the message is getting through. The defensive structure looked tighter, the transitions quicker, and the attacking combinations more purposeful than they had been seven days earlier.
Of course one game does not make a season. Leverkusen still have work to do to re-establish themselves among the consistent challengers. The Europa League campaign will bring extra fixtures. Squad depth will be tested. But afternoons like this — dominant, clinical, enjoyable to watch — are exactly what the BayArena needs after a transitional period.
Summary
Bayer Leverkusen responded to their opening-day setback with a comprehensive 4-0 victory over Union Berlin. Goals from Equi Fernández (1′), Facundo Medina (28′), Patrik Schick (48′) and Ibrahim Maza (66′) sealed a first Bundesliga win for new coach Carles Martínez. Miguel Gutiérrez provided two assists and was outstanding at left-back. Leverkusen dominated possession, restricted Union to zero shots on target, and looked every bit a side finding its rhythm.
For the home fans it was a welcome release. For Martínez it was proof that his ideas can translate quickly. For Union it was another difficult afternoon on a ground where they have never won in the top flight.
The season is still young. But on a sunny Saturday in early September, Leverkusen reminded everyone that when they click, they remain a dangerous proposition. The scoreline was emphatic. The performance was controlled. And for the first time under the new coach, the BayArena felt like a place where big things might still happen.
