William Saliba has made a significant step in his recovery from a back injury that kept him out of action for three and a half months. The Arsenal center back has returned to full training, just a day before the team's Champions League match against Slavia Prague. Manager Mikel Arteta expressed his satisfaction with Saliba's progress, stating that he 'feels very comfortable' and has been playing 45 minutes behind closed doors. Arteta also mentioned that Saliba's evolution has been as expected, which is a positive sign for his return to the team. Saliba's partnership with Gabriel Magalhães was a key factor in Arsenal's Premier League win last season, and his return could strengthen the team's defense. However, Arteta may not rush him back into the starting lineup, as summer signing Ezri Konsa has been performing well and has formed a strong partnership with Magalhães. The manager has options at right back, including Jurriën Timber and Ben White, which could also impact Saliba's immediate return to the team. Overall, Saliba's return to full training is a positive development for Arsenal, and fans will be eagerly waiting to see him back on the pitch.
