West Ham have completed the signing of Manuel Lanzini on a four-year contract from Al-Jazira.
The 23-year-old midfielder had been on loan from UAE club Al-Jazira and has now sealed a permanent switch to Upton Park. The deal, which includes an option for a further two years, is understood to be worth around £9 million.
Boss Slaven Bilic has now secured the futures of three of his key players after Dimitri Payet and Cheikhou Kouyate recently signed new long-term contracts.
Lanzini is back to full fitness following a spell on the sidelines with a thigh injury. The Argentinian scored his fifth league goal of the season with a fine 20-yard curler in the 2-2 draw at Chelsea on Saturday.
France playmaker Payet has taken most of the spotlight for West Ham this season but Lanzini also played a very important part.
