Born in London on 21 November 2000 (age 25), Matt O’Riley is a Denmark international centre midfielder now with Brighton & Hove Albion, where he wears squad number 33. His route to the Premier League ran through MK Dons, but his career took its proper shape after Celtic moved for him in January 2022 for around £1.5m.
At Celtic, O’Riley developed from a tidy, promising midfielder into one of the side’s main creative forces. Across four seasons he made 93 league appearances and scored 25 league goals, with the 2023-24 campaign his clear peak: 18 goals in 37 league games from midfield is not a detail that needs much dressing up.
Celtic sold him to Brighton & Hove Albion in August 2024 for around £25m, a substantial return on a player signed from League One two and a half years earlier. His current market value is around £17m, according to Transfermarkt.
In 2025-26, O’Riley has made six league appearances for Brighton, scoring once, and has also featured twice for Denmark in European World Cup qualifying. His career is still developing, but its strongest stretch so far came at Celtic, where the promise became production and the fee became hard to argue with.
