West Ham: Cheikhou Kouyate joins from Anderlecht
West Ham United have completed the signing of Senegalese midfielder Cheikhou Kouyate on a four-year deal from Anderlecht.
Kouyate, capped 11 times by Senegal, moves to Upton Park for an undisclosed fee.
He helped Anderlecht win four league titles after joining them in 2008.
"I am very happy because today West Ham have given me the chance to play in the Premier League," said the 24-year-old.
"For my part, I'm going to try to do great things here and try to improve further still as a player."
Kouyate, who played for Senegal against Great Britain at the London 2012 Olympics, can also play in defence.
West Ham joint-chairman David Sullivan told the club website: "We hope to have at least four more signings in place by the time we kick off against Tottenham on 16 August as we aim for at least a top-10 finish."
Kouyate is the Hammers' second new addition of the summer, following Argentine striker Mauro Zarate.
