Callum Slattery, born on 8 February 1999 (age 27), is an English central defensive midfielder with Sheffield Wednesday. His current market value is around £383,000, according to Transfermarkt.
His career only properly settles into shape through Motherwell. Early loan football helped move him beyond the usual promise-and-potential stage, but it was at Fir Park that he became a regular senior player rather than a name waiting for a run.
Across five seasons with Motherwell, Slattery made 126 league appearances and scored 16 league goals. That is the bulk of his story so far: steady involvement, a clear role in midfield, and enough end product to avoid being filed away as merely functional. His most productive league campaign came in 2024-25, when he scored six goals in 15 appearances.
He is now at Sheffield Wednesday, wearing number 8. In 2026-27, he has made seven League One appearances and scored twice, along with one League Cup appearance, giving him eight appearances and two goals in all competitions for the club.
Slattery’s career has been shaped above all by his Motherwell spell, with Sheffield Wednesday now the next stage rather than the main body of work.
