Arsenal are looking for a new center back after William Saliba suffered a back injury that is expected to keep him out for an extended period, with reports indicating that the Gunners are considering two Premier League defenders as potential replacements. The two options are Ezri Konsa and John Stones, according to The Independent, with Arsenal exploring the possibility of signing one of the experienced England internationals to strengthen their defense while Saliba is unavailable. A move for Konsa would require Arsenal to pay a significant transfer fee to Aston Villa, where the defender remains an important player. Stones, meanwhile, could be available as a free agent after his contract with Manchester City ended.
