Born on 21st November 2000, Matt O'Riley, an England native, plays primarily as a central midfielder at Brighton & Hove Albion. Standing at 6ft 1in (1.87m) and weighing 12st 1lb (77kg), O'Riley has also had the honour of representing the Denmark national team.
Presently, his market value is estimated at roughly €20.00m, which converts to around £17m, as cited by Transfermarkt.
In July 2009, a young O'Riley joined Fulham as a trainee. During his debut season 2019 - 2020, he made a solitary first-team appearance in league matches. However, in January 2021, he transferred to MK Dons in League Two, for an undisclosed fee.
By January of 2022, O'Riley found himself making the move to Scottish giants Celtic for a fee of approximately £1.5m. This period at Celtic proved to be a significant part of his career. During the 2021 - 2022 season, he made 16 first-team appearances and netted four goals, which was a respectable start. His second season, 2022 - 2023, saw him taking part in 38 matches and scoring three goals.
However, the season of 2023 - 2024 was his standout season at the club, with an impressive 37 appearances and a whopping 18 goals to his credit. Despite only making two appearances in the 2024 - 2025 season, his overall contribution to the team was well-regarded.
After his prolific stint at Celtic, a move back to England beckoned, with a transfer to Brighton & Hove Albion in the Premier League for around £25m in August 2024. His career at Brighton has so far seen him make multiple first-team appearances and score a handful of goals. In an interesting turn of events, O'Riley went on loan to Marseille in Ligue 1 in France in September 2025, where he made 15 appearances and scored one goal, before returning to Brighton in February 2026 upon completion of his loan.
O'Riley's international career includes participating in the 2024 - 2026 World Cup Qualifiers for Denmark, where he made two appearances as a substitute.
