Matt O'Riley is an English born footballer who primarily plays as a central midfielder for French side, Marseille. Born on the 21st of November, 2000, he stands tall at 6 foot 1 inch (1.87m) and weighs about 12 stone 1 pound (77 kg). Despite his British birthright, O'Riley has chosen to represent Denmark at the international level. According to Transfermarkt, his current market value is circling around £19m.
Starting his career as a trainee with Fulham in the Premier League in England in July 2009, O'Riley had a rather quiet tenure, only making a single appearance during the 2019-2020 season. In January 2021, he made a move from Fulham to MK Dons in England's League Two for an undisclosed fee.
His career really took a promising turn when he transferred from MK Dons to Celtic in Scotland's Premiership for a fee of around £1.5m in January 2022. O'Riley quickly made a mark at Celtic, making 16 appearances and scoring four goals in the remainder of the 2021-2022 season. The following season, he made 38 appearances and notched three goals. The 2023-2024 season was a true breakout for O'Riley at Celtic, with an impressive tally of 18 goals from 37 appearances. His final season in Scotland, 2024-2025, although cut short, saw him clock two appearances for Celtic.
O'Riley's impressive stint at Celtic caught the eye of English Premier League side, Brighton & Hove Albion, and he was transferred for a handsome sum of £25m in August 2024. Over the course of the 2024-2025 season, O'Riley made 21 appearances for the Seagulls and scored twice. The current 2025-2026 season has seen him make a further two appearances and one goal for Brighton.
Throwing a bit of variety into his career, O'Riley was loaned out to Marseille in France's Ligue 1 in September 2025, and has already clocked up an appearance in the current season. Topping off O'Riley's impressive career to date are his commendable appearances for Denmark in World Cup Qualifiers Europe 2024-2026 and the Euro Qualifiers 2022-2024 as well as his involvement in the Champions League 2025-2026 for Marseille.
