The Hammers have been among Europe’s busiest operators in the summer transfer window, with Soler’s arrival late on deadline day meaning they have added nine players to new manager Julen Lopetegui’s squad.
“I am really excited to be here as a West Ham player,” Soler said to club channels.
“It has always been a dream of mine to play in the Premier League, and to be doing it in London with a Club like West Ham is an incredible feeling.
“I can’t wait to feel the support of the fans, who I have already heard so much about from conversations with people who know the Club, like my good friend Pablo Fornals.
