Sivert Heltne Nilsen, pegged from his homeland Norway, is a central defensive midfielder brandishing the number 6 and currently plying his trade for Aberdeen. Nilsen first saw the world on 2 October 1991, making him 33 years of age. Standing at 6ft (1.84m) and tipping the scales at 12st 3lb (78kg), the Norwegian commands quite a presence in the midfield. In the arena of market value, he sits comfortably around the £325k mark, as indicated by Transfermarkt. His commitment to Aberdeen remains firm until 30 June 2027, with 2 years and 5 months remaining.
The Norwegian’s journey started with Hødd in the OBOS-ligaen back in 2009, but in 2014 took a leap to Valerenga in the Eliteserien. He made a commendable 41 first-team appearances across two seasons. The narrative then drifted towards Brann in July of 2015 where he soon became a familiar face in the first team. Across seasons peppered with goals, Nilsen made a total of 158 appearances in league matches for Brann.
By the time July 2018 rolled around, he was transferred from Brann to AC Horsens in Denmark's 1. division. seasons here were followed by a transfer to IF Elfsborg in the Swedish Allsvenskan in August 2019.
After contributing with his fair share of appearances and the occasional goal, a call from Belgium saw him transferred from IF Elfsborg to the Belgian side, Waasland-Beveren in the Derde Klasse. Although the commitment cost them around £400k, Nilsen only made nine first-team appearances in the 2020-2021 season.
A return to Norway's Brann was staged in August 2021, where Nilsen made a familiar mark with multiple appearances and goals. By July 2024, though, Aberdeen would become his new home. Aberdeen shelled out around £300k to bring the Norwegian to the Scottish Premiership. In the ongoing 2024-2025 season, he's graced the pitch 25 times for Aberdeen already.
Aberdeen fans watch him as he continues to represent the side resolutely in the cups too - he's made six starts in the League Cup 2024-2025, and has taken to the pitch twice in the Scottish Cup 2024-2025.
