Arsenal's 2-0 Carabao Cup final loss to Manchester City exposed costly errors and harsh selection calls. Mikel Arteta's decision to start Kepa Arrizabalaga backfired, while late substitutions worsened the performance. Nico O'Reilly's brace sealed City's ninth crown, leaving Arsenal to reflect on mistakes and regroup for bigger ambitions in the Premier League, FA Cup, and Champions League.
