Jakob Breum Martinsen (born 17 November 2003) is a Danish professional footballer who plays as an attacking midfielder or winger for club Go Ahead Eagles.
Born in Odense, Breum began his youth career with local side Ubberud IF before moving to Næsby Boldklub, both feeder clubs of OB. He joined OB's academy in 2018. On 6 March 2019, he signed his first professional contract with the club, a three-year deal.
Breum made his senior debut on 7 June 2020, coming on as a substitute in a 3âÂÂ1 Danish Superliga win over Esbjerg fB. At 16 years and 203 days, he became the third-youngest player to make a competitive appearance for OB. On his 18th birthday, 17 November 2021, he extended his contract until June 2026. He scored his first professional goals on 3 April 2022, netting twice in a 2âÂÂ1 league win against Nordsjælland. Later that season, he appeared as a substitute in the Danish Cup final against Midtjylland, which OB lost on penalties after a 1âÂÂ1 draw following extra time.
In June 2023, Breum joined Dutch Eredivisie club Go Ahead Eagles, signing a four-year contract until 2027. He scored his first goal for the club on 4 February 2024, coming off the bench in a 2âÂÂ0 victory over Vitesse. The following month, he netted the winner in a 1âÂÂ0 home defeat of RKC Waalwijk.
In the 2024âÂÂ25 season, Breum was used primarily as an attacking midfielder after earlier appearances on the wing. On 10 January 2025, he scored a hat-trick in a 3âÂÂ0 away win at Fortuna Sittard. He was named the Johan Cruyff Talent of the Month for February 2025. Later that month he sustained a foot fracture in a match against Ajax, ruling him out for an extended period. He finished the campaign with 26 league appearances, 10 goals and five assists, and 31 appearances and 11 goals in all competitions.
Breum represented Denmark at under-17 level in 2020, making four appearances. He also played twice for the under-18s, scoring both goals on his debut in a 3âÂÂ1 victory over Germany on 4 September 2019. At under-19 level he made nine appearances and scored seven goals between 2021 and 2022, and he progressed to the under-21s in 2023, earning six caps.
