Omeruo was found by Chelsea’s scouts in Colombia in 2011 when he was representing the Nigeria team at the Under-20s World Cup finals, then aged just 17, he was specifically the kind of composed, ball-playing centre-back the club denoted in recruiting.
The 25-year-old has put an end to his seven years drought in Chelsea without playing a game.
Omeruo acquired a permanent move to Leganes following an impressive loan spell last season with the Spanish club.
It was understood that Leganes paid a sum of £4.6million for the Nigerian international, who has penned a five-year contract deal with the club.
Omeruo joined Chelsea in 2012 from Standard Liege, but he couldn’t make his debutant for the Blues instead he spent most of his time on loan in Holland, Turkey, Spain and with Championship club Middlesbrough.
However, Omeruo’s performances for Leganes last season have persuaded them to purchase him outright.
He helped them finish tenth on the Laliga table last season, after making 31 appearances for the club.
Omeruo made 50 caps for his country and represented the Super Eagles in 2014 and 2018 Fifa World Cups, he also won the African cup of nations for Nigeria five years ago.
