Arsenal lose Gyokeres, Arteta warns of challenges in Prague.

Arsenal enter the fourth round of the Champions League classification with a major blow to their attack: Viktor Gyokeres is unavailable due to a muscle injury. Mikel Arteta also confirmed four long-term knee injuries and stressed that Slavia Prague are unbeaten at home this season, posing a significant physical and mental challenge.

Arsenal's squad situation before the match against Slavia Prague

Before departure, Arteta confirmed: “Victor Gyokeres will not be able to play. He didn’t train today and we need more tests and scans to understand the extent of the injury. I’m worried because he’s usually never had muscle problems, and having to leave the pitch because something seems wrong is never a good sign.”

The Spanish manager also described the injury situation in the attacking line as "unusual," with four knee injuries: "We've looked at everything, but there are currently four knee injuries involving Gabriel Jesus, Kai Havertz, Noni Madueke, and Martin Odegaard — which is quite rare, and all of them are long-term. The rest are muscle injuries in other players, which can happen to any team. We have to deal with it, and so far the whole team has done very well."

Tactical dilemma when firepower is insufficient.

Arsenal will likely have to adjust their approach to compensate for the depleted attacking line. Arteta insists the team's response will continue to rely on collective organization and exemplary "individual conduct" in defense and transitions. Given the limited personnel, managing the tempo and minimizing errors in key areas will be a priority: maintaining structure when losing possession, ensuring midfield coverage, and choosing the right moments to accelerate on the counter-attack.

With the substitution window narrowed, every personnel decision is strategic: who provides depth, who moves to stretch the defense, and who acts as a target man in direct attacks. The lack of a constant threat in attack demands that Arsenal increase the effectiveness of short-pass combinations and make the most of gaps created by opponent errors, rather than engaging in unnecessary one-on-one duels.

Slavia Prague and the away test

Arteta showed clear respect for Slavia Prague: “We were prepared for a really tough game. Slavia have been together for a long time, are unbeaten at home all season and create a passionate atmosphere.”

The mental aspect therefore becomes a significant variable. Against a vibrant crowd, the ability to handle periods of pressure — for example, after an opponent's acceleration or after set pieces — will be a measure of character. Calmness, emotional control, and discipline in the team's structure can determine how the game unfolds, especially with Arsenal being affected by injuries in the attacking line.

The significance of the fourth round of the Champions League classification.

Matchday 4 often shapes the trajectory of the remainder of the season. Given their depleted squad, Arsenal's priority is preserving their foundation: solid defensive transitions, alertness in first-touch challenges, and efficiency in half-hearted chances. Every point carries significant weight as they enter the final stretch.

Selective statistics

• Viktor Gyokeres: muscle injury, unavailable for training and unable to play (according to Arteta).
• Four players with long-term knee injuries: Gabriel Jesus, Kai Havertz, Noni Madueke, and Martin Odegaard.
• Slavia Prague: Unbeaten at home since the start of the season, passionate atmosphere (Arteta's assessment).

In that context, Arsenal's tactical awareness and ability to control the tempo will be tested to the extreme. A disciplined performance could be key to overcoming the high-pressure 90 minutes in Prague.
