West Ham have announced the signing of Spain international attacking midfielder Pablo Fornals from Villarreal.
Fornals, 23, has agreed a five-year contract with the Hammers, which includes the option of a 12-month extension.
West Ham said Fornals has become "the second-most-expensive signing in the club's history behind Felipe Anderson", the Brazilian having signed last summer in a reported £34million deal.
Fornals is set to feature for Spain at the European Under-21 Championships in Italy.
"I'm very happy to be part of West Ham," Fornals told the club website.
"I feel very good, very happy and very grateful for the opportunity that has been provided to me.
"I want the club to continue giving opportunities to young and ambitious people, people who want to do well for the long term."
