West Ham United have completed the signing of Spanish striker Lucas Perez from London rivals Arsenal.

The 29-year-old joins the Hammers after putting pen to paper on a three-year contract in a deal worth £4m including add-ons.

He becomes the eighth signing of the summer after Ryan Fredericks, Lukasz Fabianski, Issa Diop, Jack Wilshere, Aindriy Yarmolenko, Fabian Balbuena and Felipe Anderson.

Lucas Perez signed for Arsenal from Spanish side Deportivo La Coruna in a £17m deal in 2016 but found limited opportunities at the Emirates Stadium and was loaned back for the 2016/17 season.

In his first interview as a Hammer, Lucas Perez said: “I’m very happy to be here at such an historic Club.”

“I’m very excited, as West Ham are giving me the chance to stay in the Premier League and I’m very happy to be part of this new project.

“West Ham have great fans and play in an amazing stadium, so to sign here brings me great joy. I’m very motivated.” He further stated.

The club’s director of Football Mario Husillos added: “We welcome Lucas to West Ham United.”

“He is a very experienced player that Manuel and I both know well from Spain.

“He has great technical quality, and can play as both the main striker or the second striker in a deeper role. He scores goals, but can also create them and link well with the midfielders.

“His style is different from the other strikers we have available to us, and that gives the manager more options for our attacking play.

“Lucas also has experience of the Premier League with Arsenal, and is familiar with life here in London, which of course means that he will take less time to adapt and be ready.

“From the very first meeting I had with Lucas, he made it very clear that he wanted to come to West Ham United and, for us, this is very important. We wish him every success during his time here.” He concluded.
