Mariona Caldentey stepped up in the dying moments of the match, converting a second‑half stoppage‑time penalty to give Arsenal a thrilling 1‑0 triumph over Danish outfit HB Køge as the Gunners kicked off their Women’s Champions League campaign at Meadow Park. Renee Slegers, the Arsenal manager, made a bold overhaul to her starting eleven, introducing eight fresh faces compared with the side that had drawn 1‑1 against Manchester United in the previous Women’s Super League fixture. The changes signalled a fresh tactical approach and a desire to inject new energy into the squad. In the first half, Chloe Kelly appeared to have broken the deadlock when her shot found the back of the net.

However, after a VAR review the goal was disallowed. The review determined that Stina Blackstenius, who had been involved in the build‑up, was offside when the ball was played to Kelly, nullifying the effort. Arsenal struggled to create clear‑cut chances for much of the opening period, but a turning point arrived when Selina Cerci was brought down inside the penalty area. Caldentey, who had been introduced as a substitute, stepped up and calmly placed the spot‑kick into the bottom corner, securing all three points for the visitors.

The match featured a series of contentious moments. Greek referee Eleni Antoniu initially pointed to a penalty after Kelly was fouled by Alberte Vingum in the 12th minute, but the decision was overturned following the off‑side call on Blackstenius.

Later, in the 25th minute, Maanum forced a save, and the ball rarely left Arsenal’s half until a deflected strike from Macy Schultz rattled the crossbar. Maanum attempted a cross‑shot that missed her teammate, while Kyra Cooney‑Cross also sent a powerful effort wide of the target. After the interval, Blackstenius was substituted for Alessia Russo, and Arsenal generated a flurry of chances in what began as a more open second half. Smilla Holmberg earned a free‑kick, which goalkeeper Vingum punched away.

Despite the pressure, Arsenal failed to capitalize on set‑pieces and watched as Maanum’s effort sailed over the bar. Holmberg cleared a dangerous ball after Emelia Oskarsdottir’s cross fell loose, and later her corner struck the crossbar by mere inches. The decisive moment came in the third minute of added time.

Yukina Sakabe’s challenge on Cerci resulted in a penalty award. Antoniu pointed to the spot, and Caldentey calmly slotted the ball past Vingum, sealing the win.

After the match, Arsenal Women’s coach Renee Slegers praised her side on the club’s official website, saying: "I’m delighted with the three points and the mentality we showed. The resilience to score late goals is something we’re building. We dominated much of the game but struggled to find the net until the end. The mental strength we displayed will be a cornerstone for the season." She continued, "We have five new players making an impact from day one.

Selina created the penalty, Mariona converted it, and both came off the bench. That’s the kind of contribution we expect from the whole squad. I’m proud of the collective effort and the attitude shown." In a separate fixture, Manchester City’s Women’s team staged a dramatic comeback at the Allianz Arena, turning a 2‑0 deficit into a 2‑2 draw against Bayern Munich, thereby becoming the first English side to avoid defeat to the German giants in European competition.

City’s German international Carlotta Wamser was left unmarked in the box to finish the equaliser in the 86th minute, after prolific striker Khadija "Bunny" Shaw had earlier missed a penalty that would have levelled the score. The goal came after a series of events that highlighted both City’s perseverance and Bayern’s occasional lapses. The first half had seen Bayern dominate, taking a 2‑0 lead within the opening 30 minutes.

Giulia Gwinn’s clever chip over goalkeeper Ayaka Yamashita opened the scoring in the 11th minute, following a swift break by Linda Dallmann. Bayern continued to press, with Klara Bühl and Pernille Harder both testing City’s defence, but City managed to pull one back just before halftime. Kerstin Casparij’s run down the right flank resulted in a cross that Beth Mead tapped in, reducing the deficit to 2‑1.

The goal was contentious, as a flare had been thrown onto the pitch during the build‑up, but the referee allowed play to continue and the goal stood. City’s comeback was aided by a bizarre incident involving Bayern goalkeeper Ena Mahmutovic, who appeared indecisive when confronting Aoba Fujino.

After initially allowing the ball to go out of play, Mahmutovic abruptly stuck out a leg, bringing down the City winger and conceding a free‑kick that led to a crucial moment. Shaw, who had been due to be substituted, missed the ensuing penalty, prompting an immediate substitution. However, Wamser’s composure in the 86th minute ensured City salvaged a point.

Midway through the second half, Bayern continued to threaten. Harder delivered a cross that Casparij mishandled, inadvertently directing the ball into her own net, which gave City a 2‑2 equaliser and sparked celebrations among the visitors. City midfielder Sam Coffey reflected on the match, stating on the club’s website: "Beth’s goal before the break shifted the momentum. We were more forward‑looking in the second half and that helped us turn the game around.

While we are disappointed not to have won, earning a point away from home in such a tough environment is something we can be proud of." She also highlighted the depth of the squad: "One of the strengths of our team is the quality we have on the bench. We have many game‑changers, and anyone who comes on can make a difference. That’s what the best teams in the world need, and we possess it in abundance." Both matches showcased the growing competitiveness of women’s football in Europe, with Arsenal demonstrating the impact of tactical flexibility and late‑game composure, while Manchester City proved their resilience and depth by clawing back a point against a formidable Bayern side.

The outcomes underline the importance of mental strength, squad rotation, and the ability to seize key moments in high‑stakes continental fixtures.
