Huddersfield defender Jordan Williams has signed with Barnsley on a four-year deal.
The 18-year-old has joined for an undisclosed fee.
Barnsley head coach Daniel Stendel said: "Jordan will bring something a bit different to the squad and I am happy to have him in my side.
"He's very fast and clever, this is the type of player that can play how we want to play and by signing a long contract he has committed to our project here. We know he will come in and work hard and learn our style."
