Mathias Brems Jensen (born 13 March 2002) is a Danish professional footballer who plays as a left-back for Danish 1st Division club FC Helsingør.
Born in Brenderup, Brems started his career at Brenderup IF and later played for Middelfart, before joining OB.[1] In March 2019, shortly after his 17th birthday, Brems signed a two-year youth contract with OB.[2]
After helping the U19 team lifting the trophy in the Danish U19 league, Brems got his official and professional debut for OB in a Danish Superliga game on 4 July 2020 against SønderjyskE.[3] Brems started on the bench, before replacing Oliver Lund in the 58th minute.[4] Brems was also subbed in, in the following game against Silkeborg IF.
In December 2020, Brems signed his first professional contract, running from 1 July 2021 and two years onwards, which also secured him a permanent promotion to the first team squad from the summer 2021.[1] In the 2019-20 season, Brems only made one appearance for OB's first team, which was in the Danish Cup. In the following 2021-22 season, Brems played just 110 minutes over three games for OB's first team.
In June 2022, he went on a trial at AC Horsens.[5] However, it did not result in a contract for young Brems, who therefore returned to Horsens, where he had a contract until 2023.[6]
After a trial at Horsens in June 2022, Brems tried his luck again, this time with a trial at Danish 1st Division club FC Helsingør. a few days later.[7] On 5 July 2022 the club confirmed, that they had signed Brems permanently on a deal until June 2024.[8]
In January 2024, Brems extended his contract until June 2026.[9]
