Ísak Andri Sigurgeirsson

Ísak Andri Sigurgeirsson came up through the ranks at UMF Stjarnan, joining the club's youth system in 2015 and working through the U14, U16 and U19 age groups before making his senior debut there in 2020. A loan to ÍBV in the second half of 2021 gave him regular football in the Icelandic second tier before he returned to Stjarnan, where he stayed until July 2023, when IFK Norrköping signed him.

The move to Sweden was followed by a loan to Danish club Viborg FF for the 2024/2025 season, a spell that came with an option to buy. Viborg chose not to exercise it, with injuries affecting his ability to hold down a regular place. Sigurgeirsson returned to Norrköping in July 2025 and remains part of the squad for the 2025/2026 season, in which the club competes in the Superettan following relegation from the Allsvenskan.

At international level, Sigurgeirsson has represented Iceland through the youth ranks: two caps and a goal at U16 level in 2019, the same return at U17 that year, four caps and a goal at U19 in 2021–2022, and ten caps at U21 between 2022 and 2024. He has not yet been capped by the senior national side.

Right-footed and standing 175 cm tall, Sigurgeirsson has built his career so far on a steady progression from Icelandic youth football into Scandinavian senior leagues.
