Mariona Caldentey's stoppage-time penalty rescued Arsenal Women from a frustrating UEFA Women's Champions League opener against HB Køge. The victory gives Renée Slegers' side three points, but 21 attempts and only two on target underline a finishing problem Arsenal cannot afford to carry deeper into the season.

For more than 90 minutes, Arsenal Women appeared destined for one of the most frustrating results imaginable.
They controlled possession.
They created opportunities.
They pushed HB Køge deeper and deeper.
But the goal refused to arrive.
Then, deep into stoppage time, substitute Selina Cerci was brought down inside the penalty area and Mariona Caldentey converted the resulting penalty to secure a dramatic 1–0 victory.
Arsenal's official match report confirms Caldentey's late intervention gave the Gunners a winning start to their 2026/27 Women's Champions League league-phase campaign.
Three points secured.
Crisis avoided.
But this was far from a convincing European performance.
Arsenal Dominated Without Finding the Goal
The statistics tell the story.
Arsenal registered 21 attempts compared with HB Køge's four, yet managed only two efforts on target.
HB Køge managed one.
That difference between territorial dominance and actual goal threat should concern Slegers.
Arsenal had enough possession and enough opportunities to settle this match comfortably.
Instead, the Danish visitors remained alive until stoppage time.
Kyra Cooney-Cross and Frida Maanum both threatened in the opening half, while Arsenal continued applying pressure after the interval.
Smilla Holmberg hit the crossbar directly from a corner and Leah Williamson fired over from close range as frustration grew around Meadow Park. UEFA's official Matchday 1 report documented Arsenal's repeated attempts to find the breakthrough.
The problem wasn't creating pressure.
It was turning pressure into goals.
Chloe Kelly Thought She Had Given Arsenal the Lead
Arsenal did put the ball into the net during the first half.
Chloe Kelly appeared to have opened the scoring after Alberte Vingum initially kept out an Arsenal effort.
But VAR intervened.
Stina Blackstenius was adjudged to have been offside while interfering with the goalkeeper's line of vision, and the goal was disallowed.
It was another frustrating moment in a night filled with them.
Arsenal continued to attack, but HB Køge defended with discipline and Vingum produced an assured performance in goal.
The longer the match remained scoreless, the greater the pressure became.
Eight Changes Showed Slegers Was Looking Ahead
The starting XI also provided important context.
Slegers made eight changes from the Arsenal side that drew with Manchester United at the weekend.
Only Leah Williamson, Steph Catley and Stina Blackstenius retained their starting places.
The rotation was understandable.
Arsenal are entering a demanding stretch of domestic and European football, and squad management will be essential.
The starting XI against HB Køge was:
Anneke Borbe; Smilla Holmberg, Leah Williamson, Steph Catley, Taylor Hinds; Frida Maanum, Kim Little, Kyra Cooney-Cross; Chloe Kelly, Stina Blackstenius, Caitlin Foord.
UEFA's official Champions League line-up page confirms the XI.
Rotation itself wasn't the problem.
Arsenal still fielded more than enough attacking quality to win comfortably.
The concern was what they did with that quality.
Kyra Cooney-Cross Was Arsenal's Standout Performer
One Arsenal player did emerge with significant credit.
Kyra Cooney-Cross was named UEFA's official Player of the Match.
The midfielder was influential as Arsenal attempted to control the contest and break down Køge's defensive structure.
UEFA's Technical Observer Group selected Cooney-Cross as the game's standout performer.
Her performance offers Slegers another positive option in midfield as Arsenal attempt to balance domestic and European commitments.
But Arsenal needed somebody further forward to provide the decisive moment.
Eventually, two substitutes delivered it.
Selina Cerci Changed the Match
With the clock moving beyond 90 minutes, Arsenal needed someone to force the issue.
Cerci did exactly that.
The substitute drove into the penalty area and was brought down by Yukina Sakabe.
Penalty.
After an evening of missed opportunities, Arsenal finally had the chance they needed.
Caldentey stepped forward.
There was enormous pressure attached to the kick.
She converted.
1–0 Arsenal.
The relief around the stadium was obvious.
Steph Catley later praised both substitutes, with Arsenal publishing her reaction under the headline “Big credit to Selina and Mariona”.
That is exactly why having a deep squad matters in European competition.
When the starting XI cannot solve the problem, the bench must provide another solution.
Cerci and Caldentey did.
But Arsenal's Finishing Problem Cannot Be Ignored
This is where the result becomes more interesting than the scoreline.
Winning 1–0 means Arsenal accomplished the immediate objective.
But 21 shots producing only two on target is not sustainable against Europe's strongest teams.
Against HB Køge, Arsenal eventually escaped.
Against Barcelona, OL Lyonnes or another European heavyweight, they may not receive so many opportunities.
Clinical finishing often separates Champions League contenders from Champions League winners.
Arsenal cannot expect to dominate matches indefinitely while wasting opportunities and assume a breakthrough will eventually arrive.
Sometimes it won't.
That is the warning hidden inside this victory.
Arsenal Have a Difficult European Road Ahead
The league-phase schedule becomes considerably tougher from here.
According to UEFA's official fixture list, Arsenal's remaining matches include Paris FC, Benfica, Barcelona, OL Lyonnes and Inter.
Their schedule is:
September 30: Paris FC vs Arsenal
October 28: Arsenal vs Benfica
November 11: Barcelona vs Arsenal
November 19: Arsenal vs OL Lyonnes
December 16: Inter vs Arsenal
That is a demanding European programme.
Barcelona and Lyon in particular will punish wastefulness far more severely.
So although Arsenal can celebrate three points tonight, Slegers will know there is significant work ahead.
The New Champions League Format Leaves Little Margin for Error
This is also only the second season of the Women's Champions League's league-phase format.
Eighteen teams compete across six matchdays.
The top four advance directly to the quarter-finals, while teams finishing fifth through 12th enter knockout-phase play-offs.
That makes every point valuable.
Arsenal therefore deserve credit for finding a way to win a match that appeared destined to end scoreless.
European campaigns aren't always built on spectacular performances.
Sometimes successful teams simply survive difficult nights.
This was one of those nights.
But Arsenal will know survival alone won't be enough when the opposition becomes stronger.
Three Points Matter More Than Perfection — For Now
There are two ways to view Arsenal's opening European performance.
The optimistic interpretation is straightforward.
Slegers rotated heavily, Arsenal dominated the match and still found a way to win when time was disappearing.
That demonstrates depth and persistence.
The more cautious interpretation is equally valid.
A team with Arsenal's attacking quality should not require a stoppage-time penalty to convert such overwhelming territorial superiority into a victory over HB Køge.
Both things can be true.
Arsenal deserved the victory.
And Arsenal need to become considerably more ruthless.
Caldentey's Goal Could Still Prove Important
Champions League campaigns are often shaped by moments that seem relatively small when they happen.
Caldentey's penalty earned Arsenal two additional points that appeared to be disappearing.
Those points could eventually influence league-phase positioning, direct qualification or knockout seeding.
That is why the manner of victory shouldn't completely overshadow its importance.
Arsenal started their European campaign with a win.
UEFA's Matchday 1 results confirm the Gunners alongside the opening-night winners after their 1–0 victory.
The performance can be improved.
The points cannot be improved upon.
Arsenal got all three.
Now Slegers Must Find the Ruthlessness
The biggest task for Slegers isn't creating an entirely different Arsenal.
Much of the structure worked.
They controlled territory.
They restricted HB Køge.
They generated opportunities.
The final action was the problem.
Better finishing would have transformed this from a nervous 1–0 escape into a comfortable European victory.
That means the solution may be less about tactical reinvention and more about execution.
Sharper movement inside the penalty area.
Better final passes.
More composure when chances arrive.
And greater ruthlessness.
Those details will determine how far Arsenal can go in Europe this season.
Beyond the Final Whistle, Arsenal Women achieved the most important objective by opening their Champions League campaign with three points, and Mariona Caldentey deserves credit for delivering under enormous stoppage-time pressure. But the 1–0 scoreline should not hide the warning. Twenty-one attempts and only two on target is a level of wastefulness Europe's strongest teams are unlikely to forgive. Arsenal escaped tonight; now Renée Slegers must make sure they become more clinical before the bigger European tests arrive.
Was Arsenal's narrow victory simply an early-season European battle, or should their lack of cutting edge already concern Renée Slegers? Join the conversation on Beyond the Final Whistle.
