BREMEN, Germany (Interstat) — Serhou Guirassy came off the bench to score the opening goal and Yan Couto added a stoppage-time strike as Borussia Dortmund defeated Werder Bremen 2-0 on Saturday, May 16, 2026, in the Bundesliga season opener at Weserstadion.

Guirassy, a second-half substitute, broke the deadlock in the 59th minute, finishing off a Dortmund buildup that had pinned Bremen deep in its own half. Couto sealed the result in the fifth minute of second-half stoppage time, burying a chance after a corner kick was only partially cleared by the Bremen defense.

The victory gave Borussia Dortmund a 1-0 record in the Bundesliga, matching its overall mark across all competitions to start the season. Werder Bremen fell to 0-1 in the league and 0-1 in all competitions after the defeat on its home pitch.

Dortmund controlled large stretches of the match, particularly in the second half, as Bremen struggled to generate consistent attacking threats. The hosts managed only a few speculative efforts on goal, none of which seriously tested Dortmund goalkeeper Gregor Kobel.

The loss extended Bremen’s recent frustrations against Dortmund at Weserstadion, where the visiting side has frequently found success. Bremen’s defense held firm for nearly an hour before Guirassy’s arrival shifted the momentum decisively in Dortmund’s favor.

Guirassy’s goal came after a patient passing sequence carved open the Bremen back line. The forward collected a through ball just inside the penalty area and slotted a low shot past the goalkeeper to the far post. Couto’s late goal, a close-range finish, ensured there would be no late drama.

The match was the first of the Bundesliga season for both clubs, with Dortmund looking to build on a strong preseason. Bremen, meanwhile, faces an early test of resilience as it seeks its first points of the campaign.

In the buildup to the game, Interstat’s game simulator had projected a final score of Borussia Dortmund 2, Werder Bremen 1, and Interstat’s ELO system had given Borussia Dortmund a 63.20 percent probability to win.
