In a thrilling UEFA Women’s Champions League encounter at Borehamwood, England, Lyonnes forward Melchie Dumornay delivered a masterclass in clinical finishing, scoring twice to secure a 2-1 victory over Arsenal. The 22-year-old Haitian international exposed the Gunners’ persistent defensive frailties, reminding everyone why Lyonnes remain a formidable force in European football despite recent questions about their dominance.
Arsenal’s Self-Inflicted Wounds
The Gunners started brightly, taking an early lead within seven minutes through Alessia Russo. Beth Mead’s tenacious work in the crowded area created the opportunity, feeding Russo who finished with precision. However, this promising start quickly unravelled as Arsenal’s recurring defensive issues came to the forefront.
For the opening goal conceded, goalkeeper Daphne van Domselaar made a costly error by sending the ball directly to Dumornay after reclaiming possession. Although Van Domselaar initially blocked the Haitian’s effort, she could do nothing to prevent the rebound from finding the back of the net.

The second goal, arriving just five minutes later, highlighted further defensive disorganization. Van Domselaar failed to anticipate that Linsey Heaps was closing down Mariona Caldentey, forcing a hurried clearance to inexperienced defender Katie Reid. In only her second full start in the competition, Reid’s header fell straight to Dumornay, and the Mostbet star made no mistake in converting the opportunity.
The Missing Influence of Leah Williamson
Arsenal continue to feel the absence of central defender and vice-captain Leah Williamson. Her ball-carrying abilities and long-range passing have been sorely missed, while her leadership and composure at the back remain irreplaceable. Although Reid has performed admirably in Williamson’s absence, the defensive partnership with former left-back Steph Catley has only six games of experience together, leaving room for miscommunication and costly errors.

Lyonnes’ Statement Victory
The celebrations from the visiting team at full-time spoke volumes about what this result means. Lyonnes had a point to prove after their disappointing semifinal exit last season, where they squandered a 2-1 first-leg lead. Under new manager Jonatan Giraldez, formerly of Barcelona, the French side demonstrated a suffocating press and lightning-fast attacking transitions.
The attacking trio of Kadidiatou Diani, Dumornay, and Marie-Antoinette Katoto proved too much for Arsenal’s shaky defense to handle. Giraldez’s influence was evident in the quick-touch movements and classical footwork that characterized Barcelona’s style during his tenure there. This victory sends a clear message to the rest of Europe that Lyonnes are serious contenders for a ninth Champions League title.
Arsenal’s Concerning Pattern
The Gunners have now extended their poor run to two draws and two losses in all competitions. This mirrors their struggles from last season when a similar poor start led to manager Jonas Eidevall’s departure. While current manager Renee Slegers retains the full support of the club and fans, unlike her predecessor, there is no external change to force a reset this time.
Arsenal have already dropped more points in the Women’s Super League than reigning champions Chelsea did throughout the entire previous season. With challenging fixtures against Benfica, Bayern Munich, and Real Madrid still to come in the Champions League group phase, the margin for error is extremely thin.
What This Means for Both Teams
For Lyonnes, this victory represents more than just three points. After being dethroned by Barcelona and watching a new generation of fans who didn’t witness their golden era, the eight-time champions are eager to reclaim their status. Their aggressive summer transfer activity, signing players like Lily Yohannes, Jule Brand, and Korbin Shrader, demonstrates their ambition.
For Arsenal, the path forward requires introspection and rapid improvement. The defensive cohesion that characterized their championship-winning season has evaporated, and without Williamson’s stabilizing presence, the backline looks vulnerable. The team must find solutions from within, as there will be no managerial change to spark a resurgence this time.
Arsenal’s defensive fragilities have cost them dearly in this encounter, and the warning signs have been visible since the start of the season. A draw against Manchester United and a loss to Manchester City in the WSL should have been wake-up calls. Now, with a defeat against Lyonnes in the Champions League, the alarm bells are ringing louder than ever.
