Leganes have confirmed the signing of Chelsea defender and Nigeria international Kenneth Omeruo on a five-year deal.
The 25-year-old had been on a season-long loan deal at the Madrid-based club and he had been hopeful a permanent switch is agreed this summer.
A report in Marca earlier this month claimed a €4.5m bid had been lodged by Lega with the West London club and it is thought the deal has gone through for that amount.
The central defender has not made a competitive appearance for the Blues since joining from Standard Liege in 2012 and became Chelsea’s 32nd loan exit of the summer when moving to Madrid last year.
Omeruo, who has won 51 international caps, has previously had loan spells at ADO Den Haag, Middlesbrough and Alanyaspor, alongside two separate spells at Kasimpasa
