Leganes have a deal in place for Barcelona striker Jose Arnaiz.
Onda Cero says Leganes have settled on a €6m fee with Barca for the young forward.
Arnaiz only moved from Real Valladolid last summer for €3.4m - and they along with Real Sociedad were also keen.
Barca have included a buy-back option in the deal.
Arnaiz was forced to write off the second-half last season due to a pelvic injury.
