Leeds United make first summer signing

The USA under-23s international has penned a two-year deal with United and is well known to new Leeds goalkeeping coach Richard Hartis, having worked with him at previous club Cardiff City.

Horton, who joined Cardiff from Peterborough United last summer and was understudy to David Marshall and Simon Moore, is likely to provide back-up for number one Marco Silvestri.

The 20-year-old was born in London but moved to America at the age of nine and went on to gain a soccer scholarship at North Carolina University, which he turned down in favour of a move to English football.

Having been brought across to England on the recommendation of former Tottenham goalkeeper Brad Friedel, the youngster joined Posh on a three-year deal back in 2013 - ahead of linking up with Cardiff.

Rosler said:“We had Charlie on our radar through our goalkeeping coach Richard Hartis – he had worked with him at Cardiff.

“I know the manager and assistant manager of the USA team and they gave him a glowing reference. We’re very happy with him.

“He has fantastic physical attributes and is a really positive character. He really wants to learn.

“He worked with Richard Hartis at Cardiff and we appreciate the fact that we can work with him again – that was a big factor in him coming to join us.”

Ohio-raised Horton, who is fresh from international duty with the USA U23s, said: “I’m really excited.

“Any time you can come to a club like Leeds, where all the players are hungry for success and hungry to move up the table and back to where the club belongs in the Premier League, that’s every players dream.

“To be a part of that is something I’d love to have on my resume.

“I’ve heard nothing but good things about Leeds United as a club.”
