Sean McArdle, born 27 August 2007 (age 18), is a Scottish centre midfielder whose senior career has so far been shaped mainly by Partick Thistle. He made five league appearances for Thistle across one season without scoring, a modest record, but still the clearest body of first-team football attached to him.
Celtic entered the picture in January 2026, when McArdle joined from Partick Thistle. That move gave him an early Celtic connection in a career still short on senior evidence, rather than a long-established profile to pick apart.
His current market value is around £85,000, according to Transfermarkt. At this stage, McArdle’s career is a brief one: a handful of league appearances at Partick Thistle, then a move to Celtic while still a teenager.
