Simon Grayson has further added to his squad with the signing of West Brom’s Callum McManaman.
McManaman, 26, has joined the Black Cats on a two-year deal until June 2019.
The pacy winger burst onto the scene at Wigan, making more than 100 senior appearances.
He also picked up an FA Cup winners’ medal with the Latics, being named man of the match in a 1-0 win over Manchester City in the final.
McManaman became Tony Pulis’ first signing as West Brom manager in January 2015 as the winger returned to the top flight.
He played 25 games for the Baggies and added a further 12 appearances during a loan spell with Sheffield Wednesday in the second half of last season.
