Armstrong Oko-Flex was born in Dublin on 2 March 2002 (age 24) and came through a familiar kind of academy route for a talented wide player, leaving Arsenal for Celtic in September 2018. He arrived with a decent reputation, though at Celtic that is never quite the same thing as a guarantee of a first-team path.
His Celtic spell was an early staging post rather than the main body of his senior career. In July 2021 he left for West Ham United, and his career then moved through a few testing steps: West Ham, Botev Plovdiv, Levski Sofia and a more settled period at FC Zurich. The Botev spell was productive, with six league goals in 14 appearances in 2025-26.
Now primarily a left winger for Levski Sofia, Oko-Flex remains a regular first-team presence in 2026-27. He has made 21 appearances in all competitions for the club, scoring six goals, including four goals in nine league appearances. He has also been used in European qualifying and Europa League matches, so his role has not been confined to domestic filler.
His career so far has been shaped by early promise at Arsenal and Celtic, a move into the English senior system with West Ham, and a later run of more meaningful football on the continent. At 24, he is still building the kind of sustained club record that turns academy pedigree into something more substantial.
