Sunderland have added three new signings to their U23 squad, with Sam Wilding, Bobby Beaumont, and Vinnie Steels joining the club.
The trio have each signed one-year deals and will become part of Elliott Dickman's development side next season.
Midfielder Wilding came through the youth system at West Bromwich Albion and the 20-year-old impressed on trial with the Black Cats last season. He has also spent a loan spell with National League North side Leamington.
Defender Beaumont was previously with Wrexham where the 18-year-old made a couple of first-team appearances, and he is a former Wales Schools' FA captain.
Winger Steels started out in Sunderland's academy but later moved on to Darlington, York City, and then Burnley, but the 19-year-old has now returned to Wearside.
Sunderland U23 coach Dickman said: "We had the lads in training before lockdown so we're fully aware of their capabilities, but it's nice to add some new faces to the group.
"Bobby is a good character and he's willing to learn. He can also play anywhere along the backline, so that's a big plus for us.
"We had Sam on trial last season and he was really keen to join us.
"He's a defensive midfielder that loves to break up play and he's technically very good.
"Vinnie was with us when he was younger and he's had a bit of a journey playing men's football at a young age.
"He's a quick, direct winger and we're really looking forwardto working with him.
"They are all welcome additions to the squad ahead of what we hope will be a successful season."
