From there, Oko-Flex’s career moved through West Ham, Botev Plovdiv, Levski Sofia and FC Zurich. His most productive league season came with Botev Plovdiv in 2025-26, when he scored six goals in 14 appearances.

At Levski Sofia in 2026-27, he has made 18 appearances and scored six goals in all competitions, including four goals in nine league matches and two in eight Champions League qualifiers. It is a career built across strong academy settings and senior spells in England, Scotland, Bulgaria and Switzerland, with his best returns coming after leaving Celtic.
