Cristhian Mosquera misses Arsenal training session before Napoli match

Arsenal defender Cristhian Mosquera did not participate in team training at the Sobha Realty Training Centre on Tuesday morning. His absence follows a muscular injury sustained during a recent match against Aston Villa, which also caused him to miss Sunday’s Premier League win over Chelsea. Manager Mikel Arteta noted that the club continues to monitor the progress of the injury, though the player remains a doubt for Wednesday’s Champions League opener. Arsenal is scheduled to face Napoli at the Diego Armando Maradona Stadium on Wednesday night. In other team news, Jurrien Timber participated in the training session as he continues his recovery from a long-term injury. The squad is expected to travel to Italy later on Tuesday to prepare for the fixture.
