Born on 2 October 1991 in Norway, Sivert Heltne Nilsen is an adept central defensive midfielder well known in the Scottish football scene, currently sporting the number 6 jersey for Aberdeen. Standing 6ft (1.84m) tall and weighing 12st 3lb (78kg), he brings a physical presence to the heart of the midfield. Currently, his market value is estimated to be around £209,000, this tally is corroborated by Transfermarkt.
Heltne Nilsen's football journey started with Hødd in the OBOS-ligaen in Norway, having joined their ranks in January of 2009. Following his five season stint, he transferred to Valerenga in the Eliteserien in Norway in January 2014. Over the course of two seasons, he made 41 first team appearances in league matches.
In July 2015, he then made a strategic transfer to Brann, another top-tier Norwegian club, his stint yielded a total of 139 first team appearances and 16 goals over the course of multiple seasons.
His strength and capacity impressed beyond the borders of Norway, leading to a switch to AC Horsens in the 1. division in Denmark in July 2018. His spell in Denmark, however, was comparatively brief - lasting only two seasons, during which he made 27 first team appearances and chalked up a single goal to his name.
Heltne Nilsen continued his Nordic tour with a move to IF Elfsborg in the Allsvenskan in Sweden in August 2019. Two seasons with Elfsborg saw him participating in 33 first team league matches and scoring twice.
In January of 2021, he ventured out of Scandinavian territories, joining Waasland-Beveren in the Derde Klasse in Belgium. His transfer fee, reportedly worth roughly £334,000, demonstrated the club's faith in his abilities. During his short stint, he made nine first team appearances in league matches.
However, Heltne Nilsen couldn't stay away from his home country for long, and he returned to Brann in the Eliteserien in Norway in August 2021. Consolidating his pivotal role in the team once more, his multiple seasons were marked by consistent performances and a favourable goal tally.
His current abode since July 2024 has been with Aberdeen in the Premiership in Scotland, a status upgrade facilitated by a transfer fee of around £250,500. In addition to 26 first team appearances in his debut season, he's already made seven appearances in the current 2025 - 2026 season. His involvement extends beyond the Premiership, featuring in the League Cup, Europa League Qualifiers, and Conference League for Aberdeen, with a total of two starts and three substitute appearances, scoring once in the process.
