Arsenal forward Lucas Perez has joined West Ham United for a fee believed to be in the region of £4million.
The 29-year-old joined the Gunners from Deportivo La Coruna back in 2016 for a reported fee of £17.1million.
He has since gone on to make just 11 league appearances for Arsenal and then returned to Deportivo on loan last season, where he scored eight goals in 35 games.
He has joined Manuel Pellegrini's Hammers on a three-year deal, becoming their eighth signing of the summer and the second from the Gunners after Jack Wilshere signed on a free earlier in the summer.
New Arsenal manager Unai Emery is preparing for his first season in the Premier League and has brought in a number of new faces to the Emirates, while Perez joins Wilshere, Calum Chambers and Chuba Akpom in leaving this summer.
