Mika Biereth

Arsenal

Biereth joined Premier League side Arsenal after starting with Fulham, and signed his first professional contract on 30 July 2021. He scored three goals in a 6–1 away win over Chelsea Under-23s at Kingsmeadow in the Premier League 2 on 19 September 2021, sealing his first hat-trick for Arsenal Under-23s. In May 2022, following a string of impressive performances, Biereth was one of eight players to be nominated for the Premier League 2's Player of the Month Award for April, though it was eventually awarded to West Ham United's Sonny Perkins. Biereth appeared four times as an unused substitute for Arsenal's first team during the 2021–22 season: in the FA Cup third round match away to Nottingham Forest at City Ground on 9 January, in the two legs of the EFL Cup semi-finals against Liverpool at Anfield on 13 January and at Emirates Stadium on 20 January, and in the game of the 23rd round of Premier League at Emirates Stadium against Burnley on 23 January.

Loan to RKC Waalwijk

Biereth joined Eredivisie club RKC Waalwijk on a season-long loan on 23 June 2022. On 17 September 2022, he made his competitive debut for the club in a 5–1 home victory over SC Cambuur in the domestic league. On 7 October, he scored his first and second competitive goals as a substitute in a 3–2 win over Groningen at Euroborg in the league, helping the team record the first away victory of the season.

Biereth joined Scottish Premiership side…

Born in England, Biereth is of Danish-German descent through his father, although Danish coach Lars Knudsen incorrectly attributed this to his Bosnian Serb mother. He represented Denmark at under-19 level. He was first called up by Denmark U19 in September 2021, and made his debut for the team in a 2–0 away win over Northern Ireland U19 on 6 October 2021. In March 2023 he was called up by Denmark U21 and in March 2025 by the senior national team. Besides Denmark, he also would have been eligible to represent Germany, England, Bosnia and Herzegovina and Serbia.

Biereth has been described as a robust player, possessing an all-round skillset and a knack of scoring goals. His style of play, especially his aggression and defensive contribution has been likened to Jamie Vardy. Like Vardy, he is most comfortable as a classic "number 9", or secondarily on the wing. During his time at Arsenal's Hale End academy, he developed his general and tactical play.

Biereth was born in London to a Danish-German father and a Bosnian Serb mother. He developed through Fulham's youth ranks. He finished the 2020–21 season as the top scorer in the Under-18 Premier League South, with 21 goals and 13 assists.
