Yan Valery has completed his move to Hillsborough from French club Angers.
It signals a reunion for the 25-year-old with manager Danny Rohl, who was on the coaching staff at Southampton when Valery was progressing at St Mary’s, via the club’s academy.
He made 43 Premier League appearances for the Saints after making his debut in 2018, before moving to Angers four years later.
Valery can operate on the right side of defence or in midfield and becomes Rohl’s third close-season signing.
