Callum Slattery, born on 8 February 1999 (age 27), is an English centre midfielder now with Sheffield Wednesday, where he wears number 8. His current market value is around £383,000, according to Transfermarkt.
His career was shaped less by a spectacular breakthrough than by steady senior football. Early loan spells helped move him from development football into the weekly demands of the first-team game, but Motherwell became the main body of his work.
Across five seasons at Fir Park, Slattery made 126 league appearances and scored 16 league goals. That is the spell that gives his career its shape: a long, substantial run in Scottish football, with enough edge and output from midfield to remain a regular part of the side. 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 13 appearances in all competitions, including 12 in League One, and scored three goals. It is a career built mainly on the Motherwell years, with Wednesday now the next stage rather than the headline act so far.
