Omeruo, 25, joined the Blues in January 2012 but has not made a debut in a competitive game for the London side, Concise News reports.
He has been on loan with Dutch side ADO Den Haag, English Championship club Middlesbrough, Turkish Super Lig’s Alanyaspor and Kasimpasa.
And in August 2018, the Super Eagles star joined the Cucumber Growers for his seventh loan move from Chelsea, with an option of making the deal permanent.
He has thus far helped the team to keep ten clean sheets in 24 appearances and has over time expressed his desire to remain in Spain and stabilize his career.
“I want to stay in Spain but right now the club needs to pay or reach an agreement with Chelsea,” he said.
“I know they are working towards it and will reach a decision soon. I just want to keep playing well.”
He added: “I’ve seen the importance of playing where Nigerians can watch they can see me every week and know how improved my game has been.
“I want to stay in Spain, maybe a bigger club. If not, the Leganes. I think this year is the year where I stay as I need a home.”
