Melker Ellborg

Malmö FF

Ellborg began training with IFK Berga's senior team when he was 12. He notably made his senior debut at age 13, playing 20 minutes of a friendly game vs. Älmeboda/Linnaryd. He trialed as a teen with Juventus, but ahead of the 2019 season he chose to sign for Malmö FF. He spent two years in the club’s academy before being promoted to the first team prior to the 2021 season. For three successive years, Ellborg was loaned out to three different Scanian clubs, IFK Malmö, Ariana FC, and Trelleborgs FF. In February 2025, acting on the advice of new goalkeeping coach Zlatan Azinović, previously the U19 goalkeeping coach, the club extended his contract by four years and chose to keep hold of Ellborg as a back-up keeper. Because of Johan Dahlin's ACL injury and Brazilian goalkeeper Ricardo Friedrich dwindling form, Ellborg was selected for his Malmö FF debut on 18 May 2025, keeping a clean sheet in a 3–0 win against Halmstads BK. With Sweden international Robin Olsen's arrival in the summer of 2025, Ellborg saw his playing time diminish. He ended the season with five clean sheets in seven Allsvenskan games, and was heavily praised for his Europa League campaign. As a result of his strong performances despite not being a nailed on starter, at the end of 2025 Manchester United reportedly held an interest in signing Ellborg.

Ellborg is a youth international for Sweden.

His longtime goalkeeping coach Zlatan Azinović has described Ellborg as having an "exceptional gripping technique".

Although he was born and raised in Kalmar, already as a child Ellborg supported Malmö FF due to the influence of his best friend. Ellborg’s paternal grandfather's brother, Folke Ellborg, was chairman of Kalmar FF between 1972–1976 and then 1989–1993.
