Arsenal defender set to miss Napoli game

WHAT HAPPENED
Arsenal will be without Cristhian Mosquera for their Champions League trip to Napoli tomorrow after the defender failed to recover from a muscle problem sustained against Aston Villa last month. Mosquera missed the 2-1 league victory over Chelsea and has not yet returned to training, so he was omitted from the travelling party.

With Mosquera sidelined, Ezri Konsa — a summer signing — made his first appearance in central defence against Chelsea and partnered Gabriel Magalhães effectively. Meanwhile, Jurrien Timber has completed full training again following a persistent groin issue and is available for selection for the Napoli match.

KEY CONTEXT
- Mosquera, who previously played for Valencia, picked up a muscle injury in the Premier League fixture with Aston Villa and has not recovered sufficiently to resume training.
- Konsa’s arrival at Arsenal was intended to strengthen defensive depth; he made his central-defence debut in Mosquera’s absence and was praised for his performance alongside Gabriel.
- Timber’s return to full training marks the possible restoration of another defensive option that had been limited by a groin complaint.

WHY IT MATTERS
Arsenal enter a Champions League opener short one of their central defenders, which changes manager Mikel Arteta’s selection choices for a key away fixture. Konsa’s recent solid display provides an immediate internal solution, while Timber’s fitness recovery offers an additional option. The situation also raises questions about Mosquera’s short-term availability for upcoming domestic matches.

WHAT TO WATCH NEXT
- Whether Mosquera resumes training and is fit for selection after the Napoli trip.
- Arteta’s starting backline in Naples: will Konsa keep his place, and does Timber start after returning to full training?
- Confirmation on Mosquera’s likelihood of being involved against Sunderland in the next league match, given reports that he seems unlikely to be available.

KEY FACTS
- Mosquera injured a muscle against Aston Villa last month and has not returned to training.
- He missed the 2-1 win over Chelsea and was left out of the travelling squad for the Napoli game.
- Ezri Konsa debuted in central defence and performed well alongside Gabriel Magalhaes.
- Jurrien Timber has returned to full training after a groin issue and could feature tomorrow.
