Armstrong Oko-Flex was born in Dublin on 2 March 2002 (age 24) and came through Arsenal before Celtic took him north in September 2018. A left winger, he arrived with a decent academy pedigree, though his Celtic connection remained more developmental than definitive.
He left Celtic in July 2021 for West Ham United, with his senior career then taking shape away from Scotland. After West Ham came spells in Bulgaria with Botev Plovdiv and Levski Sofia, with FC Zurich also part of the more settled period of his career after those earlier moves.
His best league return came at Botev Plovdiv in 2025-26, when he scored six goals in 14 appearances. At Levski Sofia in 2026-27, he has made 15 appearances in all competitions and scored six goals, including two in Champions League qualifying.
Oko-Flexโs career has moved from academy football at Arsenal and Celtic into a broader senior route through England, Bulgaria and Switzerland. The Celtic spell was an early staging post rather than the main body of the work.
