Leganes have acquired defender Kenneth Omeruo from Chelsea on a permanent transfer, the clubs have announced.
Omeruo, 25, starred with Leganes on loan last term, making 31 appearances for the club, 30 of which were starts.
Earlier this month, Goal reported that Chelsea were holding out for £6 million (€7m/$8m) for Omeruo, but the Blues have accepted a bid of around £4.6m.
Omeruo signed for Chelsea in 2012 from Standard Liege, but was never able to make the breakthrough into the first team at Stamford Bridge.
The Nigeria international took in several loan stints during his time at Chelsea, including with ADO Den Haag in the Netherlands and Middlesbrough in England, as well as Kasu0131mpasa and Alanyaspor in Turkey.
