West Ham have confirmed the signing of Uruguayan defender Walter Lopez on a one-year contract.
The 22-year-old was a free agent after leaving River Plate and had attracted interest from across Europe.
However, having impressed during a trial period at Upton Park, he has decided on a switch to England.
He has already earned three caps for his country, while his attacking instincts mean he is equally comfortable operating in a midfield role if required.
Hammers caretaker manager Kevin Keen admits he has been impressed by the youngster during his time at the club and is tipping him to be a success.
"Walter is a very attacking full-back who can get forward," Keen told the club's official website.
"Like (fellow new recruit) David Di Michele, he is another West Ham-type player who will hopefully show everyone at the club what he can do."
Lopez has previously enjoyed spells in Spain and Mexico but is delighted to have arrived in the Premier League.
"I am really happy to be here and I hope to have a good career," he said.
"Upton Park is a beautiful stadium and it will be great to play for West Ham. I am looking forward to it.
"It is a great club and there are some great players at the club. I know about many of them like Lucas Neill and Craig Bellamy. Everyone has made me feel very welcome.
"I watch the Premier League all the time on TV. It is the No.1 league in the world, the best and it is great to be part of it.
"I am very happy that I am here and I get to play for West Ham. The fans are very passionate and I hope to show them what I can do."
