Arsenal left Prague with three Champions League points, but their second-half performance exposed problems that Mikel Arteta cannot afford to ignore. A commanding 2–0 half-time advantage became an uncomfortable 2–1 victory as Slavia Prague transformed the contest into a relentless attacking examination of the Gunners’ defensive organisation.
The result in Arsenal vs Slavia Prague was another important step in the north London club’s European campaign. Noni Madueke opened the scoring in the ninth minute, before Viktor Gyökeres doubled the advantage in the 38th minute. However, Wiktor Nowak’s 90th-minute goal ensured Arsenal had to endure a nervous finish at the Fortuna Arena.
For Arteta, the victory delivered what mattered most: three points and an extended unbeaten Champions League run. Yet the match also raised five significant questions about Arsenal’s ability to manage pressure, protect leads and maintain tactical control when opponents change their approach.
This was not simply a case of Slavia Prague scoring a late consolation. Their second-half performance exposed weaknesses that more clinical European opponents could exploit.
1. Arsenal vs Slavia Prague: Second-Half Collapse Exposed a Serious Problem
The biggest concern from Arsenal’s Prague escape was the extraordinary difference between their first-half and second-half performances.
For the opening 45 minutes, Arsenal looked like a team capable of controlling the match. They pressed intelligently, moved the ball with authority and punished Slavia whenever opportunities appeared. Gyökeres played a central role in both goals, first creating the opening for Madueke before finishing a move to put Arsenal two goals ahead.
The second half, however, told a completely different story.
Slavia increased their intensity, committed more players forward and began attacking Arsenal with greater aggression. According to Opta’s match analysis, the Czech side registered 16 second-half shots worth 2.17 expected goals, while Arsenal managed only four attempts worth 0.19 xG.
That contrast is difficult to ignore.
Arsenal had gone from controlling the contest to spending long periods defending their penalty area. Slavia’s improvement was not merely about enthusiasm or home support. Their increased attacking threat forced Arsenal into repeated defensive actions and prevented the visitors from establishing the same control they had enjoyed before the break.
The lesson for Arteta is clear: a two-goal lead should create control, not complacency.
Elite teams do not necessarily need to dominate possession for 90 minutes, but they must understand how to manage different phases of a match. Arsenal struggled to do that after half-time.
Against a more ruthless opponent, such a dramatic drop in control could turn a comfortable victory into a damaging European result.
2. David Raya’s Saves Cannot Become Arsenal’s Defensive Plan
David Raya deserves significant credit for Arsenal’s victory. His interventions helped preserve a lead that was increasingly under threat, particularly when Slavia began finding space and creating dangerous opportunities around the penalty area.
One of the defining moments came when Oskar Kubiak directed a header towards goal. Raya produced an excellent reaction save, pushing the effort onto the post and preventing Slavia from reducing the deficit earlier.
He was not the only Arsenal player required to intervene. Gabriel Magalhães also produced a crucial goal-line clearance after Slavia threatened from a corner.
Those moments demonstrated the importance of individual quality. Arsenal had players capable of producing decisive defensive actions when the collective structure came under pressure.
But there is a difference between having a reliable goalkeeper and depending on him to rescue the team repeatedly.
Raya’s saves were valuable, yet the number of opportunities Slavia created suggests Arsenal allowed the match to become more dangerous than necessary.
A goalkeeper can make the difference in a difficult away fixture, but relying on repeated saves is not a sustainable defensive strategy across an entire Champions League campaign.
Arteta must therefore examine why Slavia were able to generate so many attempts after the break. Was Arsenal’s midfield losing control of the spaces in front of the defence? Were the wide defensive areas becoming too exposed? Did the team retreat too deeply and invite pressure?
Those are the questions that matter more than simply celebrating Raya’s performance.
3. Gabriel’s Heroics Highlighted Arsenal’s Set-Piece Vulnerability
Gabriel Magalhães’ goal-line clearance was another decisive moment in Prague. His positioning and awareness prevented Slavia from taking advantage of a dangerous situation and gave Arsenal an opportunity to reorganise.
However, the incident also highlighted an uncomfortable reality: Arsenal were increasingly being forced to defend emergencies inside their own penalty area.
Set-pieces are particularly dangerous in high-pressure European matches because they allow opponents to create direct attacking situations without needing to dominate possession.
Slavia’s pressure from corners and long deliveries tested Arsenal’s concentration. The defensive line had to deal with second balls, aerial challenges and players arriving in dangerous areas.
This is where Arteta must demand greater collective responsibility.
Gabriel’s intervention should be recognised as an excellent defensive action, but Arsenal cannot build their entire approach around hoping that a defender will be in the right position to clear the ball off the line.
The team must improve its organisation before the danger reaches that stage.
That includes:
- Maintaining better defensive distances during corners and long throws.
- Tracking opponents attacking the spaces around the six-yard box.
- Winning the first contact and reacting quickly to second balls.
- Avoiding unnecessary fouls and corners when under pressure.
The final goal also deserves attention. Slavia recycled a long throw through David Jurásek, and Nowak was left unmarked close to goal to finish from short range.
That was a preventable defensive situation. Arsenal had already survived several dangerous moments, yet they still allowed Slavia to find a decisive opening in the closing minutes.
4. Viktor Gyökeres Is Becoming a Crucial Attacking Weapon
While Arsenal’s second-half performance deserves criticism, there were also important positives from the victory. Viktor Gyökeres was arguably the most influential attacking player in the first half.
The Swedish striker contributed directly to both goals.
For Madueke’s opener, Gyökeres controlled David Raya’s long ball and helped release the winger into a dangerous position. His physical presence and ability to hold up possession gave Arsenal an effective route through Slavia’s defensive structure.
His own goal in the 38th minute demonstrated another important quality: composure in front of goal. After Mikel Merino played him through, Gyökeres maintained his balance and finished clinically.
The performance offered a reminder of what Arsenal need from their centre-forward. He must do more than wait for chances inside the penalty area. His ability to connect attacks, occupy defenders and create opportunities for teammates can make Arsenal considerably more unpredictable.
Against Slavia, that contribution was particularly important because it allowed Arsenal to exploit space behind the home side’s defensive line.
However, the second half also demonstrated why Arsenal need to maintain a reliable attacking outlet when defending a lead.
When a team retreats too deeply, an effective forward can provide an opportunity to relieve pressure by holding possession, winning fouls and allowing teammates to move up the pitch.
Gyökeres’ influence in the opening period was obvious. Arteta must ensure Arsenal continue to use those qualities throughout difficult matches rather than becoming disconnected from their striker when opponents apply pressure.
5. Arteta’s Game Management Must Improve Under Pressure
The fifth and perhaps most important lesson concerns the manager.
Arteta deserves credit for preparing a team that scored twice and established a strong position before half-time. Arsenal’s opening goal came from an effective direct attacking sequence, while the second demonstrated the value of winning possession high up the pitch and attacking quickly.
But football matches are not decided by the first 45 minutes alone.
Slavia changed the intensity of the contest after the interval. They attacked with greater urgency, pushed Arsenal backwards and created a series of opportunities. The Gunners struggled to respond with the same authority.
This is where game management becomes essential.
When an opponent increases pressure, a team must recognise the changing conditions and adjust. Sometimes that means changing the pressing structure. On other occasions, it requires greater midfield protection, more controlled possession or substitutions that help restore balance.
Arsenal’s challenge was not simply to defend their two-goal lead. It was to prevent Slavia from repeatedly returning to dangerous attacking positions.
Arteta’s substitutions and tactical decisions must therefore be assessed in that context. The important question is whether Arsenal managed to regain control after Slavia’s momentum increased, rather than merely surviving until the final whistle.
The late goal made the finish even more uncomfortable, but the warning signs had appeared well before Nowak found the net.
For a team with ambitions of competing for the Champions League, managing difficult periods is just as important as producing impressive attacking football.
What Arsenal Must Take From the Prague Escape
The victory against Slavia Prague should not be dismissed. Winning away from home in the Champions League is difficult, and Arsenal showed enough quality in the first half to secure a valuable result.
Madueke delivered an important attacking contribution, Gyökeres demonstrated his value, and Raya and Gabriel produced decisive defensive interventions when the team needed them.
The wider picture, however, is more complicated.
Arsenal cannot afford to interpret the final score as evidence that everything worked perfectly. Slavia’s second-half pressure exposed how quickly the balance of a match can change when the Gunners lose control of midfield spaces and allow opponents to attack their penalty area repeatedly.

The statistics underline the scale of that problem. Slavia’s 16 second-half attempts and 2.17 expected goals represent a substantial attacking threat, particularly against a side that had looked so comfortable before half-time.
The next challenge for Arteta is to turn this experience into a tactical improvement.
Arsenal must become more disciplined when protecting leads, more effective at retaining possession under pressure and more organised when defending set-pieces and second balls.
Final Verdict: Three Points, But Five Questions Remain
Arsenal’s 2–1 victory in Prague strengthened their Champions League position and extended an impressive unbeaten run in the competition. It was a result worth celebrating, but not a performance that should escape serious analysis.
The first half showed Arsenal’s attacking quality. The second half revealed the danger of losing control against an opponent with the courage and intensity to exploit defensive weaknesses.
For Arteta, the most valuable outcome may ultimately be the lessons learned rather than the three points collected.
Arsenal have demonstrated that they can score, compete and win difficult European away matches. The next step is proving they can control those matches for the full 90 minutes.
If they fail to address the warning signs from Prague, stronger Champions League opponents may not be as forgiving as Slavia.
