Emerson Palmieri has completed a permanent transfer to London rivals West Ham.

Emerson who spent last season on loan with Lyon has joined the Hammers on a four-year contract, with a one-year option, for a deal reported to be £15million.

Emerson was deemed surplus to requirements at Chelsea following the signing of Marc Cucurella.

Emerson has said he’s very happy to join West Ham.

“I’m very happy to be here and to arrive here,” said Emerson.

“It’s a big challenge for me, it’s a big team, so I’m very happy to be here and I’m ready.

“Personally, since the first day I arrived here in England, I always saw the big clubs and I always watched the big games and I knew the history about West Ham.

“The history is so, so big for this team and so when I knew about the interest for sure I said ‘Yes, let’s go, I want to go there’ and I’m here now! I can’t wait to get started in a West Ham shirt.”

Emerson would now join former Blue Kurt Zouma at West Ham, much to the delight of Everton boss David Moyes.

“We are very pleased to welcome Emerson to West Ham,” Moyes told the official West Ham website.

“He is an experienced player with a good pedigree, who has enjoyed great success at both club and international level in recent years.

“He will give us strong competition in defensive areas and brings a winning mentality that we are looking to build here at West Ham.

“We look forward to working with Emerson and wish him all the very best in his career with us.”
