Callum Slattery (born 8 February 1999, age 27) is an English central midfielder with Sheffield Wednesday, wearing squad number 8. His current market value is around £383,000, according to Transfermarkt.
His early senior football came in loan spells, the kind that tend to harden up young midfielders more effectively than reserve-team comfort. Those moves gave him first-team exposure, but his career only really found its shape at Motherwell.
Fir Park is where Slattery became a regular rather than a prospect. Across five seasons with Motherwell he made 126 league appearances and scored 16 league goals, a substantial body of work for a midfielder asked to do more than just tidy up possession. His most productive league season came in 2024-25, when he scored six times in 15 appearances.
He is now at Sheffield Wednesday. In 2026-27 he has made six League One appearances and scored two goals, with one further League Cup appearance, giving him seven appearances and two goals across all competitions for the club.
Slattery’s career is still framed mainly by Motherwell: a long, steady spell in Scotland after earlier loan football, followed by a move into the English league setup with Sheffield Wednesday.
