The injury crisis in Arsenal's defense has worsened after sources within the club, including a BBC report citing Sami Moqbel, confirmed that young defender Cristian Mosquera will be out for up to six weeks.

The Spanish player, who recently joined from Valencia, suffered an ankle injury during the team's recent match against Brentford. This is a significant blow to coach Mikel Arteta, who relies on him as an important option to cover for the current absences of the two main center-backs, William Saliba and Gabriel Magalhães, increasing the pressure on the squad ahead of a busy period of competitions.

These reports put the head coach in a real dilemma, as 21-year-old Mosquera had already begun integrating into the starting lineup alongside Piero Hincapié in recent matches, helping to fill the defensive gap.

While Arteta expressed concern about the "complexity" of Musquera's injury, his expected absence until mid-January will require the club to look for alternative and temporary solutions in the winter transfer market or to rely more heavily on the limited experienced players available to them in this crucial position.
