Leeds United have confirmed the signing of goalkeeper Charlie Horton from Cardiff City on a two-year deal.
The USA Under-23 international is manager Uwe Rosler's first signing at Elland Road.
Horton, 20, began his career with Peterborough United before moving to Cardiff in 2014.
"I know the manager and assistant manager of the USA team and they gave him a glowing reference. We're very happy with him," Rosler told the club's official website. "He has fantastic physical attributes and is a really positive character. He really wants to learn."
Horton is expected to spend time in the Leeds development squad before stepping up to the first team.
