The loss to Brighton appears to have unsettled Arsenal. Their response against Forest was a win, but it was not the kind of commanding performance that would silence doubts about their attack.
That sequence matters. A defeat followed by a narrow recovery leaves Arsenal needing to prove that the Forest result was the start of a stronger run rather than a temporary relief.
Merson’s concern is less about one poor result than the return of familiar limitations: Arsenal are finding it difficult to turn control into clear attacking authority when opponents defend compactly.
Eberechi Eze’s continuing difficulties in the Premier League have become another issue for Arsenal to manage. The midfielder’s influence has not reached the level expected, leaving more pressure on the rest of the attack to create decisive moments.
Arsenal can still carry a threat through their movement and technical quality, but Bayern represent a sharper test than Forest. Any hesitation in possession or lack of penetration is likely to be punished more severely in a Champions League contest.
Merson’s prediction is an opinion, not a settled outcome, but Arsenal’s recent sequence gives it weight. The Forest win offers a platform; it does not yet provide proof that the attacking concerns have disappeared.
Wednesday’s meeting with Bayern will reveal whether Arsenal can respond with greater ambition and purpose. A strong performance would quickly change the mood. Another cautious display, particularly if Eze remains subdued, would strengthen the argument that this team has reverted to type.
