City have won the League Cup eight times before, but this is the first time since 2021 that they have emerged victorious. It is the club's first title since 2024.
Both goals were scored by 21-year-old Nico O'Reilly within the space of four minutes.
After the hour mark, O'Reilly took advantage of a goalkeeping mistake by Kepa Arrizabalaga, and shortly afterwards he headed in to make it 2–0 from a cross by Matheus Nunes.
Viktor Gyökeres started for Arsenal and played the entire match, but contributed little beyond his presence.
Gyökeres will be a key player in Sweden's World Cup playoff against Ukraine next week.
