Sheffield Wednesday have confirmed the signing of midfielder Callum Slattery, with the former Motherwell man becoming the latest addition to Henrik Pedersen’s summer rebuild.
The Owls announced the capture on Monday, confirming that Slattery has signed a three-year contract at Hillsborough. The 27-year-old arrives after leaving Motherwell at the end of his deal, bringing top-flight Scottish Premiership experience and a reputation as an energetic, all-action midfielder.
Slattery spent five years at Fir Park after joining Motherwell from Southampton in 2021. During that time, he became an important figure in their midfield, making 148 appearances in all competitions and scoring 19 goals.
It was not always a straightforward spell. A serious ACL injury kept him out for a year, but Slattery returned last season and finished his Motherwell career strongly, helping the club secure European football before moving on this summer.
For Wednesday, this looks like a smart free-agent addition. Slattery is a central midfielder who can press, compete, progress the ball and contribute in the final third. He made 38 appearances in all competitions last season, scoring three goals and adding 10 assists, numbers that suggest he can offer more than just industry in the middle of the park.
There is also good pedigree behind the move. Slattery came through the academy system at Southampton, having previously been with Chelsea as a youngster, and made senior appearances for the Saints before loan spells with De Graafschap in the Netherlands and Gillingham in League One. He also represented England at youth level, including the Under-20 side that won the 2017 Toulon Tournament.
Wednesday needed more depth, legs and reliability in midfield, and Slattery should give Pedersen another serious option as he shapes the squad for the season ahead. With his age, experience and availability on a free transfer, this feels like the kind of signing that fits the brief: proven, hungry, and ready for a fresh challenge.
The Owls’ summer business is starting to take shape. Slattery may not be the headline-grabbing name some supporters crave, but he adds balance, bite and quality to an area of the pitch that needed attention.
Welcome to Wednesday, Callum.
