West Ham have signed Brazilian winger Luis Guilherme on a five-year contract.
The 18-year-old joins the Hammers from Palmeiras and is manager Julen Lopetegui's first signing since taking charge last month.
Guilherme will complete his move on Friday when the transfer window in the Premier League officially opens, subject to international clearance and a work permit being issued.
"I’m very happy to be signing with West Ham United, a club that trusted in my work," he told the club's website., external
Guilherme made his Palmeiras debut as a 17-year-old in 2023 and played for the club in this season's Copa Libertadores.
