West Ham have announced the signing highly-rated full-back Sam Byram on a four-and-a-half-year deal from Leeds for an undisclosed fee.
The 22-year-old was expected to move to Everton this month, having reportedly agreed terms with the Merseysiders last week.
However, the Hammers moved quickly to tie up a deal ahead of the Toffees and announced the defender had joined on Wednesday.
"I'm unbelievably proud and happy to join a club as big as this," Byram told the club's official website. "I'm just looking forward to what the future holds and hopefully I can achieve things with the team going forward.
"It's a childhood dream of mine to play in the Premier League, so to have the chance to get into a team like this and I just want to get my head down, work hard and hopefully get a chance.
"I spoke to the manager and he is one of the main reasons which attracted me to West Ham. I think he's done unbelievably well with his team so far, so I'm really looking forward to working with him and his staff.
"I'm also really looking forward to seeing the new stadium in person. That was another big part in me wanting to come here. It's a massive part of the future of the club and I can't wait to see and hopefully play in it."
