Sean McArdle is a Scottish centre midfielder, born on 27 August 2007 (age 19), whose early senior story has already looped back through Celtic. He was involved at Celtic in 2024/25, making two league appearances and collecting a Premiership title as part of that campaign.
Partick Thistle has still done most to shape his career to this point. McArdle made five league appearances across one season there, enough for his name to be tied more firmly to Firhill than to the usual churn of youth football.
He returned to Celtic in January 2026 from Partick Thistle. His current market value is around £85,000, according to Transfermarkt.
McArdle’s career remains at an early stage: a young Scottish midfielder with a Celtic medal, a short but meaningful Partick Thistle spell, and a return to Celtic now forming the next part of the story.
