West Ham have completed the signing of Ecuador striker Enner Valencia after he was given a work permit. The 24 year old striker has signed a five-year contract from Mexican club Pachuca for a fee reported to be £12m.
He said: "I want to repay the club in my performances for what they are investing in me."
In a statement, West Ham said they "fought off competition from a host of Europe's leading clubs" for Valencia.
"I really appreciate the welcome I've been given and I'm excited to be here," Valencia, who is no relation to Manchester United's Ecuador winger Antonio Valencia, told West Ham TV.
"I've already watched and read a lot about the club to learn about it - I know the fans are really passionate and I'm really glad to have signed.
"The World Cup was a good tournament for me personally, I scored three times and for my first World Cup it was a good experience, but I hope my next one is better for me and the team.
"Of course, the World Cup gives me confidence to come to Europe and I want to take and advance with this opportunity that West Ham have given to me."
