Ecuador striker Valencia joins West Ham on five-year deal

The 25-year-old has signed a five-year contract at Upton Park and the deal is subject to a successful work permit hearing, West Ham said on their website (www.whufc.com).

No fee was revealed but British media reports said the deal was worth 12 million pounds.

Valencia, 25, scored all three of Ecuador's goals at the World Cup in Brazil - two against Honduras and one against Switzerland - before the side's group-stage elimination.

He made his debut for Ecuadorian club side Emelec in 2010 and went to make more than 100 appearances before joining Pachuca in January this year. He scored 18 goals in 23 league games last season.

Valencia is West Ham's fifth summer signing following the captures of midfielder Diego Poyet from Charlton, striker Mauro Zarate from Velez Sarsfield, Anderlecht midfielder Cheikhou Kouyate and Ipswich fullback Aaron Cresswell.
